Dave Schellberg, product support specialist at Eagle Iron Works, presents tips to troubleshoot three common operational issues.

<p>The post How to solve three common challenges with fine material washers first appeared on Pit & Quarry.</p>

Fine material washers are essential components in many aggregate processing operations.

They not only help remove silt and clay from valuable sand, but they play a critical role in ensuring product quality and protecting downstream equipment from unnecessary wear.

Still, like any piece of equipment, fine material washers can experience operational issues that impact performance, efficiency and product specifications. To help producers maintain optimal performance, here are some tips to troubleshoot three of the most common issues encountered in the field, as well as practical solutions to keep screw washers running smoothly.

Before performing any of these maintenance or inspection tasks, be sure to follow all safety protocols. This includes lockout/tagout/tryout before undertaking these tasks.

1. Material buildup in the pool area

One of the most frequently observed issues in fine material washer operations is material accumulating in the washer’s pool area. This can reduce equipment efficiency and increase maintenance requirements if not corrected promptly.

Possible causes & solutions

■ Excessive screw speed. When screw washers operate too quickly, the normal settling pattern of fine particles can be disturbed and allow coarse material to accumulate in the pool.

To resolve this, reduce the screw speed to allow for proper stratification of the material. Running a screen analysis of the feed material can also help determine if the speed settings are appropriate.

For more precise guidance, contact your equipment manufacturer to ensure your screw speed is optimized for your feed gradation.

■ Inadequate silt dilution. If the washer’s overflow appears thick or syrupy, it indicates poor silt dilution. This can lead to excessive buildup.

Flush out the tub with clean water, temporarily cut the feed in half and observe if the issue persists. Increasing the clean water supply to the washer can help thin out the overflow and promote better separation.

■ Washer overload. An overloaded washer can’t properly classify and transport material. Ideally, sand should be seen just spilling over the third exposed screw flight above the waterline. If you notice a heavy buildup, reduce the feed rate to restore balance and avoid unnecessary wear on the screw flights.

2. Loss of fines from the washer

Another critical challenge in aggregate processing is the unintended loss of fines from the washer, which can negatively affect product yield and quality.

Possible causes & solutions

■ Too much water in the screen. Excess water can carry fine particles out with the overflow. To determine if fines are being lost, compare a sample of the washed feed against a sample of the final product.

Leveling the weirs and using the overflow depth to calculate gallonage can help you fine-tune the water input. Refer to a hydraulic split chart to understand the optimal water-to-material ratio and adjust accordingly.

■ Inadequate silt dilution. Another way to assess dilution efficiency is by using a hydrometer to measure the specific gravity of the washer water.

A reading above 1.065 suggests excessive silt. If this is the case, flush the washer with clean water, reduce the feed temporarily and rerun a sample analysis to evaluate the extent of fines loss.

3. Discharge too sloppy

A sloppy discharge may signal inefficiencies within the washer that can lead to problems with downstream material handling or product stockpiling.

Possible causes & solutions

■ Drainboard channel plugged. The first thing to check is the drainboard channel. If it’s plugged, water and fines can back up, leading to a slurry-like discharge.

Make sure flush water to the drainboard is turned on and that the trough is clear of any debris or settled material.

■ Dirty wash water. If the washer is running with muddy or recirculated water full of fines, it will affect the final product. Flush the washer with clean water and temporarily reduce the feed to allow the system to reset. A clearer water stream will result in a firmer, drier sand discharge that’s easier to handle and stack.

Remember …

Like any equipment in an aggregate operation, fine material washers require attention and tuning to ensure they’re operating at peak efficiency.

Many issues – from material buildup to loss of fines – can be traced back to water quality, feed consistency or mechanical settings. Routine inspections and basic sample testing – such as specific gravity or a screen analysis – are essential to diagnose these common problems.

When in doubt, operations can turn to manufacturers who offer field support, diagnostics and equipment recommendations to help operations troubleshoot and fine-tune their systems for better performance and longer equipment life.

By staying proactive with maintenance and understanding the indicative signs of trouble, producers can keep their fine material washers operating efficiently, extend component lifespan and consistently produce a high-quality sand product.

Keeney Sand & Stone’s Kevin Keeney shares midyear insights and an outlook for the coming months during an exclusive visit with P&Q.

<p>The post Ohio producer discusses first-half 2025 and what’s ahead first appeared on Pit & Quarry.</p>

Kevin Keeney, the third-generation owner and operator of Keeney Sand & Stone, paid Pit & Quarry a visit at the end of June to reflect on the first half of the year in northeast Ohio and what’s potentially ahead in the coming months.

P&Q: How has 2025 treated Keeney Sand & Stone thus far?

Keeney: I’d say I got spoiled the last four years. We’ve had pretty easy winters in northeast Ohio. My guys were usually back to mining in late February, and it stayed busy.

But this year, we had an old-fashioned winter. It held on longer than usual. The frost held in the ground, and I didn’t start calling guys back until the end of March. Jobs kept getting delayed because of that.

Once we hit April, though, things started moving again. It’s been just as busy as the past several years, and 2025 looks like it’ll be another strong year.

P&Q: Do you expect the work that got pushed aside in the first half of the year to be there for you in the second half of 2025? Also, how important will it be to extend your production season into November or beyond?

Keeney: The projects I knew were coming in 2024 are still on the way. Some are just waiting in the wings. I’m hoping winter holds off until after Christmas, but even if we get through November, we’ll have a solid finish to the year.

My production and jobs might not quite match the last three or four years, but they’ll be close. And that’s only because we had such a slow start to the year.

P&Q: What kind of construction work is keeping Keeney Sand & Stone busy right now?

Keeney: Right now, we’re involved in a lot of big school projects, parking lots and overburden jobs. We’re supplying a large amount of clay fill. New construction’s still strong – especially housing – so we’re doing a tremendous number of driveways and providing materials for a lot of commercial projects.

We haven’t seen much of a slowdown. Like any election year, last year I held off on making some purchases. Our numbers are down a little bit, but it’s strictly weather-related and not anything political.

P&Q: With tariffs and global conflicts making headlines, do you have any long-term concerns for your business or the industry?

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

The Associated General Contractors of America’s CEO and chief economist offer perspective on the construction market and the need for policy clarity.

<p>The post Report: Policy uncertainty slowing construction demand first appeared on Pit & Quarry.</p>

Leaders at the Associated General Contractors of America (AGC) say construction job growth has stalled in many parts of the U.S. amid growing uncertainty about tax, tariff and labor policy.

To illustrate its point, AGC says construction employment increased in 180 of 360 U.S. metro areas between May 2024 and May 2025.

“Only half of metro areas experienced a year-over-year gain in construction jobs – the fewest since March 2021,” says Ken Simonson, chief economist at AGC. “This appears to support other indications that investors and developers are delaying or canceling planned projects until they know how severely they’ll be affected by evolving tariff and workforce policies.”

AGC says the latest construction spending figures released in early June show construction spending declined over a 12-month period.

“While Washington is working to prevent a massive tax increase, negotiate new trade deals and hopefully boost funding for workforce development, at this point nothing is set in stone,” says Jeffrey Shoaf, CEO of AGC. “The sooner D.C. provides certainty on a host of issues, the more likely construction demand will rebound.”

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

<p>The post What operators should know about MSHA’s special assessments first appeared on Pit & Quarry.</p>

We often get calls from operators who are upset about receiving a special assessment from the Mine Safety & Health Administration (MSHA).

In many of these cases, penalties that would normally amount to a small fine under a regular assessment points calculation escalate to tens of thousands of dollars. In many of these situations, figuring out how the special assessment amount was determined can be mystifying.

While we do not necessarily have good answers, MSHA regulations and policy do provide guidance to help you anticipate a special assessment.

Inside MSHA’s process

The regulation at 30 C.F.R. § 100.5 sets out the parameters for the agency’s authority to issue special assessments. It states that MSHA may elect to waive the regular assessment process when conditions warrant.

The regular assessment process is the point system based on the operator’s violation history, the size of the operator, the level of negligence, the effect on the operator’s ability to continue in business, the gravity of the violation and the demonstrated good faith of the operator in abating the violation. The rule requires that those factors also be considered and presented with the special assessment in narrative form, although no explanation regarding the amount of the penalty calculation is required.

MSHA’s Program Policy Manual (PPM) states that special assessments are mandatory for operators when an operator has failed to abate a violation and is receiving daily penalties for that continued failure; a violation is deemed flagrant; and a violation of section 105(c) discrimination protections is made.

With that said, most special assessments arise from the exercise of MSHA’s discretion to issue higher civil penalties in nonmandatory circumstances. According to the PPM, the enforcement circumstances in which MSHA is required to evaluate whether a special assessment is warranted include the following:

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

The Associated General Contractors of America’s CEO and chief economist offer perspective on the construction market and the need for policy clarity.

<p>The post Report: Policy uncertainty slowing construction demand first appeared on Pit & Quarry.</p>

Leaders at the Associated General Contractors of America (AGC) say construction job growth has stalled in many parts of the U.S. amid growing uncertainty about tax, tariff and labor policy.

To illustrate its point, AGC says construction employment increased in 180 of 360 U.S. metro areas between May 2024 and May 2025.

“Only half of metro areas experienced a year-over-year gain in construction jobs – the fewest since March 2021,” says Ken Simonson, chief economist at AGC. “This appears to support other indications that investors and developers are delaying or canceling planned projects until they know how severely they’ll be affected by evolving tariff and workforce policies.”

AGC says the latest construction spending figures released in early June show construction spending declined over a 12-month period.

“While Washington is working to prevent a massive tax increase, negotiate new trade deals and hopefully boost funding for workforce development, at this point nothing is set in stone,” says Jeffrey Shoaf, CEO of AGC. “The sooner D.C. provides certainty on a host of issues, the more likely construction demand will rebound.”

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

<p>The post What operators should know about MSHA’s special assessments first appeared on Pit & Quarry.</p>

We often get calls from operators who are upset about receiving a special assessment from the Mine Safety & Health Administration (MSHA).

In many of these cases, penalties that would normally amount to a small fine under a regular assessment points calculation escalate to tens of thousands of dollars. In many of these situations, figuring out how the special assessment amount was determined can be mystifying.

While we do not necessarily have good answers, MSHA regulations and policy do provide guidance to help you anticipate a special assessment.

Inside MSHA’s process

The regulation at 30 C.F.R. § 100.5 sets out the parameters for the agency’s authority to issue special assessments. It states that MSHA may elect to waive the regular assessment process when conditions warrant.

The regular assessment process is the point system based on the operator’s violation history, the size of the operator, the level of negligence, the effect on the operator’s ability to continue in business, the gravity of the violation and the demonstrated good faith of the operator in abating the violation. The rule requires that those factors also be considered and presented with the special assessment in narrative form, although no explanation regarding the amount of the penalty calculation is required.

MSHA’s Program Policy Manual (PPM) states that special assessments are mandatory for operators when an operator has failed to abate a violation and is receiving daily penalties for that continued failure; a violation is deemed flagrant; and a violation of section 105(c) discrimination protections is made.

With that said, most special assessments arise from the exercise of MSHA’s discretion to issue higher civil penalties in nonmandatory circumstances. According to the PPM, the enforcement circumstances in which MSHA is required to evaluate whether a special assessment is warranted include the following:

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.

Dave Schellberg, product support specialist at Eagle Iron Works, presents tips to troubleshoot three common operational issues.

<p>The post How to solve three common challenges with fine material washers first appeared on Pit & Quarry.</p>

Fine material washers are essential components in many aggregate processing operations.

They not only help remove silt and clay from valuable sand, but they play a critical role in ensuring product quality and protecting downstream equipment from unnecessary wear.

Still, like any piece of equipment, fine material washers can experience operational issues that impact performance, efficiency and product specifications. To help producers maintain optimal performance, here are some tips to troubleshoot three of the most common issues encountered in the field, as well as practical solutions to keep screw washers running smoothly.

Before performing any of these maintenance or inspection tasks, be sure to follow all safety protocols. This includes lockout/tagout/tryout before undertaking these tasks.

1. Material buildup in the pool area

One of the most frequently observed issues in fine material washer operations is material accumulating in the washer’s pool area. This can reduce equipment efficiency and increase maintenance requirements if not corrected promptly.

Possible causes & solutions

■ Excessive screw speed. When screw washers operate too quickly, the normal settling pattern of fine particles can be disturbed and allow coarse material to accumulate in the pool.

To resolve this, reduce the screw speed to allow for proper stratification of the material. Running a screen analysis of the feed material can also help determine if the speed settings are appropriate.

For more precise guidance, contact your equipment manufacturer to ensure your screw speed is optimized for your feed gradation.

■ Inadequate silt dilution. If the washer’s overflow appears thick or syrupy, it indicates poor silt dilution. This can lead to excessive buildup.

Flush out the tub with clean water, temporarily cut the feed in half and observe if the issue persists. Increasing the clean water supply to the washer can help thin out the overflow and promote better separation.

■ Washer overload. An overloaded washer can’t properly classify and transport material. Ideally, sand should be seen just spilling over the third exposed screw flight above the waterline. If you notice a heavy buildup, reduce the feed rate to restore balance and avoid unnecessary wear on the screw flights.

2. Loss of fines from the washer

Another critical challenge in aggregate processing is the unintended loss of fines from the washer, which can negatively affect product yield and quality.

Possible causes & solutions

■ Too much water in the screen. Excess water can carry fine particles out with the overflow. To determine if fines are being lost, compare a sample of the washed feed against a sample of the final product.

Leveling the weirs and using the overflow depth to calculate gallonage can help you fine-tune the water input. Refer to a hydraulic split chart to understand the optimal water-to-material ratio and adjust accordingly.

■ Inadequate silt dilution. Another way to assess dilution efficiency is by using a hydrometer to measure the specific gravity of the washer water.

A reading above 1.065 suggests excessive silt. If this is the case, flush the washer with clean water, reduce the feed temporarily and rerun a sample analysis to evaluate the extent of fines loss.

3. Discharge too sloppy

A sloppy discharge may signal inefficiencies within the washer that can lead to problems with downstream material handling or product stockpiling.

Possible causes & solutions

■ Drainboard channel plugged. The first thing to check is the drainboard channel. If it’s plugged, water and fines can back up, leading to a slurry-like discharge.

Make sure flush water to the drainboard is turned on and that the trough is clear of any debris or settled material.

■ Dirty wash water. If the washer is running with muddy or recirculated water full of fines, it will affect the final product. Flush the washer with clean water and temporarily reduce the feed to allow the system to reset. A clearer water stream will result in a firmer, drier sand discharge that’s easier to handle and stack.

Remember …

Like any equipment in an aggregate operation, fine material washers require attention and tuning to ensure they’re operating at peak efficiency.

Many issues – from material buildup to loss of fines – can be traced back to water quality, feed consistency or mechanical settings. Routine inspections and basic sample testing – such as specific gravity or a screen analysis – are essential to diagnose these common problems.

When in doubt, operations can turn to manufacturers who offer field support, diagnostics and equipment recommendations to help operations troubleshoot and fine-tune their systems for better performance and longer equipment life.

By staying proactive with maintenance and understanding the indicative signs of trouble, producers can keep their fine material washers operating efficiently, extend component lifespan and consistently produce a high-quality sand product.

Keeney Sand & Stone’s Kevin Keeney shares midyear insights and an outlook for the coming months during an exclusive visit with P&Q.

<p>The post Ohio producer discusses first-half 2025 and what’s ahead first appeared on Pit & Quarry.</p>

Kevin Keeney, the third-generation owner and operator of Keeney Sand & Stone, paid Pit & Quarry a visit at the end of June to reflect on the first half of the year in northeast Ohio and what’s potentially ahead in the coming months.

P&Q: How has 2025 treated Keeney Sand & Stone thus far?

Keeney: I’d say I got spoiled the last four years. We’ve had pretty easy winters in northeast Ohio. My guys were usually back to mining in late February, and it stayed busy.

But this year, we had an old-fashioned winter. It held on longer than usual. The frost held in the ground, and I didn’t start calling guys back until the end of March. Jobs kept getting delayed because of that.

Once we hit April, though, things started moving again. It’s been just as busy as the past several years, and 2025 looks like it’ll be another strong year.

P&Q: Do you expect the work that got pushed aside in the first half of the year to be there for you in the second half of 2025? Also, how important will it be to extend your production season into November or beyond?

Keeney: The projects I knew were coming in 2024 are still on the way. Some are just waiting in the wings. I’m hoping winter holds off until after Christmas, but even if we get through November, we’ll have a solid finish to the year.

My production and jobs might not quite match the last three or four years, but they’ll be close. And that’s only because we had such a slow start to the year.

P&Q: What kind of construction work is keeping Keeney Sand & Stone busy right now?

Keeney: Right now, we’re involved in a lot of big school projects, parking lots and overburden jobs. We’re supplying a large amount of clay fill. New construction’s still strong – especially housing – so we’re doing a tremendous number of driveways and providing materials for a lot of commercial projects.

We haven’t seen much of a slowdown. Like any election year, last year I held off on making some purchases. Our numbers are down a little bit, but it’s strictly weather-related and not anything political.

P&Q: With tariffs and global conflicts making headlines, do you have any long-term concerns for your business or the industry?

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

Leveling the weirs and using the overflow depth to calculate gallonage can help you fine-tune the water input. Refer to a hydraulic split chart to understand the optimal water-to-material ratio and adjust accordingly.

■ Inadequate silt dilution. Another way to assess dilution efficiency is by using a hydrometer to measure the specific gravity of the washer water.

A reading above 1.065 suggests excessive silt. If this is the case, flush the washer with clean water, reduce the feed temporarily and rerun a sample analysis to evaluate the extent of fines loss.

3. Discharge too sloppy

A sloppy discharge may signal inefficiencies within the washer that can lead to problems with downstream material handling or product stockpiling.

Possible causes & solutions

■ Drainboard channel plugged. The first thing to check is the drainboard channel. If it’s plugged, water and fines can back up, leading to a slurry-like discharge.

Make sure flush water to the drainboard is turned on and that the trough is clear of any debris or settled material.

■ Dirty wash water. If the washer is running with muddy or recirculated water full of fines, it will affect the final product. Flush the washer with clean water and temporarily reduce the feed to allow the system to reset. A clearer water stream will result in a firmer, drier sand discharge that’s easier to handle and stack.

Remember …

Like any equipment in an aggregate operation, fine material washers require attention and tuning to ensure they’re operating at peak efficiency.

Many issues – from material buildup to loss of fines – can be traced back to water quality, feed consistency or mechanical settings. Routine inspections and basic sample testing – such as specific gravity or a screen analysis – are essential to diagnose these common problems.

When in doubt, operations can turn to manufacturers who offer field support, diagnostics and equipment recommendations to help operations troubleshoot and fine-tune their systems for better performance and longer equipment life.

By staying proactive with maintenance and understanding the indicative signs of trouble, producers can keep their fine material washers operating efficiently, extend component lifespan and consistently produce a high-quality sand product.

Keeney Sand & Stone’s Kevin Keeney shares midyear insights and an outlook for the coming months during an exclusive visit with P&Q.

<p>The post Ohio producer discusses first-half 2025 and what’s ahead first appeared on Pit & Quarry.</p>

Kevin Keeney, the third-generation owner and operator of Keeney Sand & Stone, paid Pit & Quarry a visit at the end of June to reflect on the first half of the year in northeast Ohio and what’s potentially ahead in the coming months.

P&Q: How has 2025 treated Keeney Sand & Stone thus far?

Keeney: I’d say I got spoiled the last four years. We’ve had pretty easy winters in northeast Ohio. My guys were usually back to mining in late February, and it stayed busy.

But this year, we had an old-fashioned winter. It held on longer than usual. The frost held in the ground, and I didn’t start calling guys back until the end of March. Jobs kept getting delayed because of that.

Once we hit April, though, things started moving again. It’s been just as busy as the past several years, and 2025 looks like it’ll be another strong year.

P&Q: Do you expect the work that got pushed aside in the first half of the year to be there for you in the second half of 2025? Also, how important will it be to extend your production season into November or beyond?

Keeney: The projects I knew were coming in 2024 are still on the way. Some are just waiting in the wings. I’m hoping winter holds off until after Christmas, but even if we get through November, we’ll have a solid finish to the year.

My production and jobs might not quite match the last three or four years, but they’ll be close. And that’s only because we had such a slow start to the year.

P&Q: What kind of construction work is keeping Keeney Sand & Stone busy right now?

Keeney: Right now, we’re involved in a lot of big school projects, parking lots and overburden jobs. We’re supplying a large amount of clay fill. New construction’s still strong – especially housing – so we’re doing a tremendous number of driveways and providing materials for a lot of commercial projects.

We haven’t seen much of a slowdown. Like any election year, last year I held off on making some purchases. Our numbers are down a little bit, but it’s strictly weather-related and not anything political.

P&Q: With tariffs and global conflicts making headlines, do you have any long-term concerns for your business or the industry?

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

The Associated General Contractors of America’s CEO and chief economist offer perspective on the construction market and the need for policy clarity.

<p>The post Report: Policy uncertainty slowing construction demand first appeared on Pit & Quarry.</p>

Leaders at the Associated General Contractors of America (AGC) say construction job growth has stalled in many parts of the U.S. amid growing uncertainty about tax, tariff and labor policy.

To illustrate its point, AGC says construction employment increased in 180 of 360 U.S. metro areas between May 2024 and May 2025.

“Only half of metro areas experienced a year-over-year gain in construction jobs – the fewest since March 2021,” says Ken Simonson, chief economist at AGC. “This appears to support other indications that investors and developers are delaying or canceling planned projects until they know how severely they’ll be affected by evolving tariff and workforce policies.”

AGC says the latest construction spending figures released in early June show construction spending declined over a 12-month period.

“While Washington is working to prevent a massive tax increase, negotiate new trade deals and hopefully boost funding for workforce development, at this point nothing is set in stone,” says Jeffrey Shoaf, CEO of AGC. “The sooner D.C. provides certainty on a host of issues, the more likely construction demand will rebound.”

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

<p>The post What operators should know about MSHA’s special assessments first appeared on Pit & Quarry.</p>

We often get calls from operators who are upset about receiving a special assessment from the Mine Safety & Health Administration (MSHA).

In many of these cases, penalties that would normally amount to a small fine under a regular assessment points calculation escalate to tens of thousands of dollars. In many of these situations, figuring out how the special assessment amount was determined can be mystifying.

While we do not necessarily have good answers, MSHA regulations and policy do provide guidance to help you anticipate a special assessment.

Inside MSHA’s process

The regulation at 30 C.F.R. § 100.5 sets out the parameters for the agency’s authority to issue special assessments. It states that MSHA may elect to waive the regular assessment process when conditions warrant.

The regular assessment process is the point system based on the operator’s violation history, the size of the operator, the level of negligence, the effect on the operator’s ability to continue in business, the gravity of the violation and the demonstrated good faith of the operator in abating the violation. The rule requires that those factors also be considered and presented with the special assessment in narrative form, although no explanation regarding the amount of the penalty calculation is required.

MSHA’s Program Policy Manual (PPM) states that special assessments are mandatory for operators when an operator has failed to abate a violation and is receiving daily penalties for that continued failure; a violation is deemed flagrant; and a violation of section 105(c) discrimination protections is made.

With that said, most special assessments arise from the exercise of MSHA’s discretion to issue higher civil penalties in nonmandatory circumstances. According to the PPM, the enforcement circumstances in which MSHA is required to evaluate whether a special assessment is warranted include the following:

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.

Dave Schellberg, product support specialist at Eagle Iron Works, presents tips to troubleshoot three common operational issues.

<p>The post How to solve three common challenges with fine material washers first appeared on Pit & Quarry.</p>

Fine material washers are essential components in many aggregate processing operations.

They not only help remove silt and clay from valuable sand, but they play a critical role in ensuring product quality and protecting downstream equipment from unnecessary wear.

Still, like any piece of equipment, fine material washers can experience operational issues that impact performance, efficiency and product specifications. To help producers maintain optimal performance, here are some tips to troubleshoot three of the most common issues encountered in the field, as well as practical solutions to keep screw washers running smoothly.

Before performing any of these maintenance or inspection tasks, be sure to follow all safety protocols. This includes lockout/tagout/tryout before undertaking these tasks.

1. Material buildup in the pool area

One of the most frequently observed issues in fine material washer operations is material accumulating in the washer’s pool area. This can reduce equipment efficiency and increase maintenance requirements if not corrected promptly.

Possible causes & solutions

■ Excessive screw speed. When screw washers operate too quickly, the normal settling pattern of fine particles can be disturbed and allow coarse material to accumulate in the pool.

To resolve this, reduce the screw speed to allow for proper stratification of the material. Running a screen analysis of the feed material can also help determine if the speed settings are appropriate.

For more precise guidance, contact your equipment manufacturer to ensure your screw speed is optimized for your feed gradation.

■ Inadequate silt dilution. If the washer’s overflow appears thick or syrupy, it indicates poor silt dilution. This can lead to excessive buildup.

Flush out the tub with clean water, temporarily cut the feed in half and observe if the issue persists. Increasing the clean water supply to the washer can help thin out the overflow and promote better separation.

■ Washer overload. An overloaded washer can’t properly classify and transport material. Ideally, sand should be seen just spilling over the third exposed screw flight above the waterline. If you notice a heavy buildup, reduce the feed rate to restore balance and avoid unnecessary wear on the screw flights.

2. Loss of fines from the washer

Another critical challenge in aggregate processing is the unintended loss of fines from the washer, which can negatively affect product yield and quality.

Possible causes & solutions

■ Too much water in the screen. Excess water can carry fine particles out with the overflow. To determine if fines are being lost, compare a sample of the washed feed against a sample of the final product.

Leveling the weirs and using the overflow depth to calculate gallonage can help you fine-tune the water input. Refer to a hydraulic split chart to understand the optimal water-to-material ratio and adjust accordingly.

■ Inadequate silt dilution. Another way to assess dilution efficiency is by using a hydrometer to measure the specific gravity of the washer water.

A reading above 1.065 suggests excessive silt. If this is the case, flush the washer with clean water, reduce the feed temporarily and rerun a sample analysis to evaluate the extent of fines loss.

3. Discharge too sloppy

A sloppy discharge may signal inefficiencies within the washer that can lead to problems with downstream material handling or product stockpiling.

Possible causes & solutions

■ Drainboard channel plugged. The first thing to check is the drainboard channel. If it’s plugged, water and fines can back up, leading to a slurry-like discharge.

Make sure flush water to the drainboard is turned on and that the trough is clear of any debris or settled material.

■ Dirty wash water. If the washer is running with muddy or recirculated water full of fines, it will affect the final product. Flush the washer with clean water and temporarily reduce the feed to allow the system to reset. A clearer water stream will result in a firmer, drier sand discharge that’s easier to handle and stack.

Remember …

Like any equipment in an aggregate operation, fine material washers require attention and tuning to ensure they’re operating at peak efficiency.

Many issues – from material buildup to loss of fines – can be traced back to water quality, feed consistency or mechanical settings. Routine inspections and basic sample testing – such as specific gravity or a screen analysis – are essential to diagnose these common problems.

When in doubt, operations can turn to manufacturers who offer field support, diagnostics and equipment recommendations to help operations troubleshoot and fine-tune their systems for better performance and longer equipment life.

By staying proactive with maintenance and understanding the indicative signs of trouble, producers can keep their fine material washers operating efficiently, extend component lifespan and consistently produce a high-quality sand product.

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.

Dave Schellberg, product support specialist at Eagle Iron Works, presents tips to troubleshoot three common operational issues.

<p>The post How to solve three common challenges with fine material washers first appeared on Pit & Quarry.</p>

Fine material washers are essential components in many aggregate processing operations.

They not only help remove silt and clay from valuable sand, but they play a critical role in ensuring product quality and protecting downstream equipment from unnecessary wear.

Still, like any piece of equipment, fine material washers can experience operational issues that impact performance, efficiency and product specifications. To help producers maintain optimal performance, here are some tips to troubleshoot three of the most common issues encountered in the field, as well as practical solutions to keep screw washers running smoothly.

Before performing any of these maintenance or inspection tasks, be sure to follow all safety protocols. This includes lockout/tagout/tryout before undertaking these tasks.

1. Material buildup in the pool area

One of the most frequently observed issues in fine material washer operations is material accumulating in the washer’s pool area. This can reduce equipment efficiency and increase maintenance requirements if not corrected promptly.

Possible causes & solutions

■ Excessive screw speed. When screw washers operate too quickly, the normal settling pattern of fine particles can be disturbed and allow coarse material to accumulate in the pool.

To resolve this, reduce the screw speed to allow for proper stratification of the material. Running a screen analysis of the feed material can also help determine if the speed settings are appropriate.

For more precise guidance, contact your equipment manufacturer to ensure your screw speed is optimized for your feed gradation.

■ Inadequate silt dilution. If the washer’s overflow appears thick or syrupy, it indicates poor silt dilution. This can lead to excessive buildup.

Flush out the tub with clean water, temporarily cut the feed in half and observe if the issue persists. Increasing the clean water supply to the washer can help thin out the overflow and promote better separation.

■ Washer overload. An overloaded washer can’t properly classify and transport material. Ideally, sand should be seen just spilling over the third exposed screw flight above the waterline. If you notice a heavy buildup, reduce the feed rate to restore balance and avoid unnecessary wear on the screw flights.

2. Loss of fines from the washer

Another critical challenge in aggregate processing is the unintended loss of fines from the washer, which can negatively affect product yield and quality.

Possible causes & solutions

■ Too much water in the screen. Excess water can carry fine particles out with the overflow. To determine if fines are being lost, compare a sample of the washed feed against a sample of the final product.

Leveling the weirs and using the overflow depth to calculate gallonage can help you fine-tune the water input. Refer to a hydraulic split chart to understand the optimal water-to-material ratio and adjust accordingly.

■ Inadequate silt dilution. Another way to assess dilution efficiency is by using a hydrometer to measure the specific gravity of the washer water.

A reading above 1.065 suggests excessive silt. If this is the case, flush the washer with clean water, reduce the feed temporarily and rerun a sample analysis to evaluate the extent of fines loss.

3. Discharge too sloppy

A sloppy discharge may signal inefficiencies within the washer that can lead to problems with downstream material handling or product stockpiling.

Possible causes & solutions

■ Drainboard channel plugged. The first thing to check is the drainboard channel. If it’s plugged, water and fines can back up, leading to a slurry-like discharge.

Make sure flush water to the drainboard is turned on and that the trough is clear of any debris or settled material.

■ Dirty wash water. If the washer is running with muddy or recirculated water full of fines, it will affect the final product. Flush the washer with clean water and temporarily reduce the feed to allow the system to reset. A clearer water stream will result in a firmer, drier sand discharge that’s easier to handle and stack.

Remember …

Like any equipment in an aggregate operation, fine material washers require attention and tuning to ensure they’re operating at peak efficiency.

Many issues – from material buildup to loss of fines – can be traced back to water quality, feed consistency or mechanical settings. Routine inspections and basic sample testing – such as specific gravity or a screen analysis – are essential to diagnose these common problems.

When in doubt, operations can turn to manufacturers who offer field support, diagnostics and equipment recommendations to help operations troubleshoot and fine-tune their systems for better performance and longer equipment life.

By staying proactive with maintenance and understanding the indicative signs of trouble, producers can keep their fine material washers operating efficiently, extend component lifespan and consistently produce a high-quality sand product.

Keeney Sand & Stone’s Kevin Keeney shares midyear insights and an outlook for the coming months during an exclusive visit with P&Q.

<p>The post Ohio producer discusses first-half 2025 and what’s ahead first appeared on Pit & Quarry.</p>

Kevin Keeney, the third-generation owner and operator of Keeney Sand & Stone, paid Pit & Quarry a visit at the end of June to reflect on the first half of the year in northeast Ohio and what’s potentially ahead in the coming months.

P&Q: How has 2025 treated Keeney Sand & Stone thus far?

Keeney: I’d say I got spoiled the last four years. We’ve had pretty easy winters in northeast Ohio. My guys were usually back to mining in late February, and it stayed busy.

But this year, we had an old-fashioned winter. It held on longer than usual. The frost held in the ground, and I didn’t start calling guys back until the end of March. Jobs kept getting delayed because of that.

Once we hit April, though, things started moving again. It’s been just as busy as the past several years, and 2025 looks like it’ll be another strong year.

P&Q: Do you expect the work that got pushed aside in the first half of the year to be there for you in the second half of 2025? Also, how important will it be to extend your production season into November or beyond?

Keeney: The projects I knew were coming in 2024 are still on the way. Some are just waiting in the wings. I’m hoping winter holds off until after Christmas, but even if we get through November, we’ll have a solid finish to the year.

My production and jobs might not quite match the last three or four years, but they’ll be close. And that’s only because we had such a slow start to the year.

P&Q: What kind of construction work is keeping Keeney Sand & Stone busy right now?

Keeney: Right now, we’re involved in a lot of big school projects, parking lots and overburden jobs. We’re supplying a large amount of clay fill. New construction’s still strong – especially housing – so we’re doing a tremendous number of driveways and providing materials for a lot of commercial projects.

We haven’t seen much of a slowdown. Like any election year, last year I held off on making some purchases. Our numbers are down a little bit, but it’s strictly weather-related and not anything political.

P&Q: With tariffs and global conflicts making headlines, do you have any long-term concerns for your business or the industry?

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

The Associated General Contractors of America’s CEO and chief economist offer perspective on the construction market and the need for policy clarity.

<p>The post Report: Policy uncertainty slowing construction demand first appeared on Pit & Quarry.</p>

Leaders at the Associated General Contractors of America (AGC) say construction job growth has stalled in many parts of the U.S. amid growing uncertainty about tax, tariff and labor policy.

To illustrate its point, AGC says construction employment increased in 180 of 360 U.S. metro areas between May 2024 and May 2025.

“Only half of metro areas experienced a year-over-year gain in construction jobs – the fewest since March 2021,” says Ken Simonson, chief economist at AGC. “This appears to support other indications that investors and developers are delaying or canceling planned projects until they know how severely they’ll be affected by evolving tariff and workforce policies.”

AGC says the latest construction spending figures released in early June show construction spending declined over a 12-month period.

“While Washington is working to prevent a massive tax increase, negotiate new trade deals and hopefully boost funding for workforce development, at this point nothing is set in stone,” says Jeffrey Shoaf, CEO of AGC. “The sooner D.C. provides certainty on a host of issues, the more likely construction demand will rebound.”

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

<p>The post What operators should know about MSHA’s special assessments first appeared on Pit & Quarry.</p>

We often get calls from operators who are upset about receiving a special assessment from the Mine Safety & Health Administration (MSHA).

In many of these cases, penalties that would normally amount to a small fine under a regular assessment points calculation escalate to tens of thousands of dollars. In many of these situations, figuring out how the special assessment amount was determined can be mystifying.

While we do not necessarily have good answers, MSHA regulations and policy do provide guidance to help you anticipate a special assessment.

Inside MSHA’s process

The regulation at 30 C.F.R. § 100.5 sets out the parameters for the agency’s authority to issue special assessments. It states that MSHA may elect to waive the regular assessment process when conditions warrant.

The regular assessment process is the point system based on the operator’s violation history, the size of the operator, the level of negligence, the effect on the operator’s ability to continue in business, the gravity of the violation and the demonstrated good faith of the operator in abating the violation. The rule requires that those factors also be considered and presented with the special assessment in narrative form, although no explanation regarding the amount of the penalty calculation is required.

MSHA’s Program Policy Manual (PPM) states that special assessments are mandatory for operators when an operator has failed to abate a violation and is receiving daily penalties for that continued failure; a violation is deemed flagrant; and a violation of section 105(c) discrimination protections is made.

With that said, most special assessments arise from the exercise of MSHA’s discretion to issue higher civil penalties in nonmandatory circumstances. According to the PPM, the enforcement circumstances in which MSHA is required to evaluate whether a special assessment is warranted include the following:

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.

Keeney Sand & Stone’s Kevin Keeney shares midyear insights and an outlook for the coming months during an exclusive visit with P&Q.

<p>The post Ohio producer discusses first-half 2025 and what’s ahead first appeared on Pit & Quarry.</p>

Kevin Keeney, the third-generation owner and operator of Keeney Sand & Stone, paid Pit & Quarry a visit at the end of June to reflect on the first half of the year in northeast Ohio and what’s potentially ahead in the coming months.

P&Q: How has 2025 treated Keeney Sand & Stone thus far?

Keeney: I’d say I got spoiled the last four years. We’ve had pretty easy winters in northeast Ohio. My guys were usually back to mining in late February, and it stayed busy.

But this year, we had an old-fashioned winter. It held on longer than usual. The frost held in the ground, and I didn’t start calling guys back until the end of March. Jobs kept getting delayed because of that.

Once we hit April, though, things started moving again. It’s been just as busy as the past several years, and 2025 looks like it’ll be another strong year.

P&Q: Do you expect the work that got pushed aside in the first half of the year to be there for you in the second half of 2025? Also, how important will it be to extend your production season into November or beyond?

Keeney: The projects I knew were coming in 2024 are still on the way. Some are just waiting in the wings. I’m hoping winter holds off until after Christmas, but even if we get through November, we’ll have a solid finish to the year.

My production and jobs might not quite match the last three or four years, but they’ll be close. And that’s only because we had such a slow start to the year.

P&Q: What kind of construction work is keeping Keeney Sand & Stone busy right now?

Keeney: Right now, we’re involved in a lot of big school projects, parking lots and overburden jobs. We’re supplying a large amount of clay fill. New construction’s still strong – especially housing – so we’re doing a tremendous number of driveways and providing materials for a lot of commercial projects.

We haven’t seen much of a slowdown. Like any election year, last year I held off on making some purchases. Our numbers are down a little bit, but it’s strictly weather-related and not anything political.

P&Q: With tariffs and global conflicts making headlines, do you have any long-term concerns for your business or the industry?

Keeney: We use a lot of steel and abrasives, so I wasn’t sure where things were going – especially when it came to screen cloth and the steel we use for fabrication. For a while, it was a bit uncertain.

But things seem to have leveled off. It felt like there was some fear at first, but it hasn’t turned into anything major. Diesel fuel prices are down, and overall, my costs haven’t risen much compared to the past.

The Associated General Contractors of America’s CEO and chief economist offer perspective on the construction market and the need for policy clarity.

<p>The post Report: Policy uncertainty slowing construction demand first appeared on Pit & Quarry.</p>

Leaders at the Associated General Contractors of America (AGC) say construction job growth has stalled in many parts of the U.S. amid growing uncertainty about tax, tariff and labor policy.

To illustrate its point, AGC says construction employment increased in 180 of 360 U.S. metro areas between May 2024 and May 2025.

“Only half of metro areas experienced a year-over-year gain in construction jobs – the fewest since March 2021,” says Ken Simonson, chief economist at AGC. “This appears to support other indications that investors and developers are delaying or canceling planned projects until they know how severely they’ll be affected by evolving tariff and workforce policies.”

AGC says the latest construction spending figures released in early June show construction spending declined over a 12-month period.

“While Washington is working to prevent a massive tax increase, negotiate new trade deals and hopefully boost funding for workforce development, at this point nothing is set in stone,” says Jeffrey Shoaf, CEO of AGC. “The sooner D.C. provides certainty on a host of issues, the more likely construction demand will rebound.”

Bill Doran and Margo Lopez of Ogletree Deakins explain how routine violations can lead to massive penalties, breaking down how the Mine Safety & Health Administration’s special assessment process works.

<p>The post What operators should know about MSHA’s special assessments first appeared on Pit & Quarry.</p>

We often get calls from operators who are upset about receiving a special assessment from the Mine Safety & Health Administration (MSHA).

In many of these cases, penalties that would normally amount to a small fine under a regular assessment points calculation escalate to tens of thousands of dollars. In many of these situations, figuring out how the special assessment amount was determined can be mystifying.

While we do not necessarily have good answers, MSHA regulations and policy do provide guidance to help you anticipate a special assessment.

Inside MSHA’s process

The regulation at 30 C.F.R. § 100.5 sets out the parameters for the agency’s authority to issue special assessments. It states that MSHA may elect to waive the regular assessment process when conditions warrant.

The regular assessment process is the point system based on the operator’s violation history, the size of the operator, the level of negligence, the effect on the operator’s ability to continue in business, the gravity of the violation and the demonstrated good faith of the operator in abating the violation. The rule requires that those factors also be considered and presented with the special assessment in narrative form, although no explanation regarding the amount of the penalty calculation is required.

MSHA’s Program Policy Manual (PPM) states that special assessments are mandatory for operators when an operator has failed to abate a violation and is receiving daily penalties for that continued failure; a violation is deemed flagrant; and a violation of section 105(c) discrimination protections is made.

With that said, most special assessments arise from the exercise of MSHA’s discretion to issue higher civil penalties in nonmandatory circumstances. According to the PPM, the enforcement circumstances in which MSHA is required to evaluate whether a special assessment is warranted include the following:

■ Regular citations alleging advance notice of inspections; denial of entry to inspectors; and failure to allow authorized miners’ representative to participate in inspection

■ Regular citations alleging a failure to comply with accident scene control orders issued under section 103(j) and (k) of the Mine Act or in conjunction with a pattern notice

■ 104(b) failure to abate orders

■ 104(d) unwarrantable failure orders

■ 104(g)(1) training orders

■ Regular citations issued in conjunction with a 107(a) imminent danger order

■ Violations that contributed to a fatal or serious injury

When one of these types of enforcement actions occur, the inspector is required to complete the Special Assessment Review (SAR) Form (MSHA Form 7000-32). The inspector will include on the form an initial penalty recommendation with a narrative in support. The form is then reviewed by the inspector’s supervisors, who support or oppose the recommendation.

The final decision regarding special assessment is made by the Office of Assessments, Accountability, Special Enforcement & Investigations at MSHA headquarters. This is a wholly internal agency procedure into which operators have no input, because special assessments are usually issued months after any informal conference, and the operator does not know what the inspector has alleged in the SAR form.

A frustrating aspect of this process is that operators generally cannot get access to the completed SAR form. MSHA takes the position – and most judges have agreed – that information in the form is not relevant because the Federal Mine Safety & Health Review Commission assesses penalties de novo and is not bound by MSHA’s proposed penalties. So, what the inspector writes in the SAR form regarding the assessment does not matter regarding the appropriateness of the penalty.

Still, in Consol Mining Co, LLC, Docket No. WEVA 2024-0231 (April 2025), one judge indicated that the SAR might be “marginally relevant” to evaluating MSHA’s high negligence and unwarrantable failure determinations in a case. Nonetheless, that judge still denied access to the SAR because it contained privileged communications of internal agency deliberations.

Final thought

Given this background, it is critical that operators recognize and anticipate when a special assessment might happen. In that circumstance, the operator can directly address the issue in an informal conference and try to have an impact on the subsequent internal agency discussions regarding the issue.
