Every state has a utility notification system or hotline that contractors use to notify utility and facility owners about their upcoming work. Once made aware of utilities on the jobsite, contractors need to follow the utility owner’s safety protocols while digging near their utilities or structures.

Markings

Facility owners respond to a contractor’s request by marking their utilities and structures on the right-of-way or the jobsite. The contractor uses these ground markings and any available survey maps to verify the utility’s and structure’s locations.

If any utility is within the contractor’s excavation pathway, workers must verify its exact location first. When the utility is underground, this can be hazardous because the contractor must rely on ground markings and survey maps to pinpoint the precise location of the utility, and those aren’t always correct. Crews should use ground-penetrating radar devices to aid their locating efforts.

Hand Digging

Workers must hand dig down to the utility and verify its exact location before using any mechanical means in the tolerance zone. After locating the utility, workers must verify its depth, size, condition, and any sharp bends or turns it makes to avoid contacting it later with mechanized equipment. Workers cannot use mechanical means while digging over the utility or within its tolerance zone.

The tolerance zone is the width of the utility, plus a specified distance from the outer edge of it, which varies in each state. In Michigan, for instance, this distance is 18 inches. For a 6 feet wide duct bank, workers cannot use any mechanical equipment within 4 ½ feet from the utility’s centerline.

Mechanical Means

Workers can use mechanical means outside the tolerance zone. Still, they should angle their excavation cuts in a particular manner so dirt from the tolerance zone slides into the excavated area. This method will minimize the amount of hand digging that’s needed.

Hard surfaces, like concrete and asphalt, should be cut into smaller pieces using a saw. Workers can pry up and remove these pieces to expose the softer ground below the hard surface. Workers can use a digging spade in the tolerance zone, but they must avoid contacting the utility while using one.

Some states allow workers to use mechanical means to remove the hard surface, but they must be careful. The utility could be in the sidewalk’s or roadway’s gravel base instead of buried below it. This is a common issue with older utilities installed before modern building codes took effect.

Key to remember

Workers must not use mechanical means while digging in a utility’s tolerance zone. Instead, they must hand dig down to the utility to verify its exact location before using any mechanical means to dig within the tolerance zone.

EHS Monthly Round Up - January 2023

In this monthly roundup video, we’ll review the most impactful environmental, safety, and health news.

Hi everyone! Welcome to the monthly roundup video, where we’ll review the most impactful environmental, safety, and health news. First, let’s take a look at what’s happening in safety and health.

If you haven’t already done so, now is the time to post your OSHA 300A Summary. Employers are required to post the Summary in a conspicuous place from February 1st through April 30th.

As required by law, OSHA increased its penalties for inflation in mid-January. Penalties went up 7.7 percent, effective January 17th.

Also in January, OSHA released its long-awaited Fall 2022 regulatory agenda. Along with numerous proposed rules in the works, three major final rules are slated for 2023 – COVID-19 in healthcare, Injury and Illness tracking, and an update to the hazard communication standard.

OSHA recently released two new letters of interpretation, which address exit signs and lockout/tagout. Specifically, OSHA states that the International Standards Organization emergency exit symbol can be located beside the mandatory EXIT text on an existing sign.

The second letter addresses the applicability of lockout/tagout and the maintenance and operations of cathodic protection rectifiers when working on pipelines.

New York’s Warehouse Worker Protection Act was signed into law in December and takes effect in late February. It protects warehouse distribution workers from undisclosed or unlawful work speed quotas and includes protections for workers who fail to meet these quotas.

In 2021, a worker died every 101 minutes from a work-related injury, according to the Bureau of Labor Statistics. A total of 5,190 fatal work injuries was recorded in the U.S. in 2021, an 8.9 percent increase over 2020.

Turning to environmental news, EPA automatically added nine per- and polyfluoroalkyl substances, or PFAS, to the Toxics Release Inventory, or TRI, list. Four PFAS were added since they are no longer claimed as confidential business information.

EPA released its Fall 2022 regulatory agenda in early January. Included are major regulations impacting the National Ambient Air Quality Standards, waters of the United States, and modifications to the Risk Management Program under the Clean Air Act.

There are also a number of rules related to the National Emission Standards for Hazardous Air Pollutants in various rule stages.

And finally, beginning with model year 2027, heavy-duty trucks will be required to meet clean air standards that are 80 percent more stringent than current requirements.

EPA says this final rule is aimed at reducing smog- and soot-forming emissions, increasing the life of governed vehicles by up to 250 percent, and increasing emissions warranty periods up to 450 percent.

Effective January 15, OSHA penalties increased 3.2 percent for inflation. Most penalties increased to $16,131. Willful and serious violations, however, increased to $161,323.

Construction workers aged 45 and older suffer more severe injuries and higher associated costs than other age groups. Most injuries are due to slips, trips, and falls.

Washington State updated its process safety management rules to better protect workers in petroleum refineries from the hazards of volatile chemicals. The rules take effect December 27, 2024.

Bloodborne pathogens topped the list of OSHA violations for the healthcare industry in 2023. Hazard Communication was the second most cited standard, followed by respiratory protection.

OSHA Region 2 launched a regional emphasis program that targets tree trimming, tree removal, and land clearing operations. Region 2 includes New York, New Jersey, Puerto Rico, and the U.S. Virgin Islands.

EPA continues to strengthen its regulation of per- and polyfluoroalkyl — or PFAS — substances. A new rule prevents facilities from using any of the 300+ inactive PFAS before EPA conducts a risk determination and, if necessary, regulates the activity.

In response to soaring temperatures across the country, OSHA issued a heat hazard alert reminding employers of their obligation to protect workers against heat illness. OSHA also ramped up enforcement activities in high-risk industries like construction and agriculture.

OSHA's annual Safe and Sound Week was held the week of August 7. It highlighted the importance of workplace safety and health programs. This year's focus was on mental health and well-being.

OSHA wants to know how you use your safety and health program to ensure a positive workplace safety culture. The agency has drawn up questions related to work safety values, safety messaging, and more, and will use your feedback to develop educational materials. November 30 is the deadline for comments.

Though the current hurricane season has been relatively quiet, it's important to be prepared as the height of the season approaches. Both OSHA and NIOSH have provided resources to help emergency responders, recovery workers, and employers prepare in advance for anticipated weather disasters.

Workplace deaths due to unintentional overdoses of fentanyl and methamphetamine continue to rise. In 2021, there were 464 such fatalities, a 19.6 percent increase over 2020.

And finally, turning to environmental news, receiving facilities will see increased user fees for the e-Manifest system in fiscal years 2024 and 2025. EPA sets these user fees based on how the manifest is submitted and processing costs for each manifest type. Using fully electronic waste manifests will cost significantly less.

Section 404 permits: Does your project need a permit to fill?
2025-01-03T06:00:00Z

Section 404 permits: Does your project need a permit to fill?

Some commercial and industrial projects place materials (called fill) in a body of water for various reasons, such as building a facility, adding a road to a facility site, or installing intake and outfall pipes at a power plant. If the project affects any of the waters of the United States (WOTUS), you must first obtain a permit.

Section 404 of the Clean Water Act requires a permit to discharge dredged or fill material into any WOTUS (including wetlands). Before conducting any activities at your facility’s site, it’s crucial to find out whether your project requires a permit to fill.

What’s considered fill material?

The regulations at 40 CFR 232.2 define fill material as any material placed in WOTUS that:

  • Replaces any part of WOTUS with dry land, or
  • Changes the bottom elevation of WOTUS.

Fill material excludes trash and garbage. Common examples of fill material are:

  • Construction debris,
  • Materials used to create a structure/infrastructure,
  • Rock,
  • Sand, and
  • Soil.

Whenever fill material is dumped, placed, or deposited in WOTUS, a “discharge of fill material” occurs. Examples (according to 232.2) range from road fills to commercial and industrial site development fills.

The Environmental Protection Agency and the U.S. Army Corps of Engineers (USACE) jointly administer the Section 404 permit program. The USACE typically issues the permits unless a state or tribal program is authorized to issue them.

Does your project require a permit to fill?

To answer this question, you’ll need to address a few more questions:

1. Will fill materials enter WOTUS?

The first step is to determine whether Section 404 regulations cover any on-site waterbodies.

The Aquatic Resource Delineation Report is a required part of the permitting process. It identifies any on-site aquatic resources (i.e., waterbodies or wetlands) subject to permitting rules. Businesses typically hire consultants to develop the report.

If you need help figuring out the status of your aquatic resources, you can request the USACE to make a written jurisdictional determination of whether Section 404 rules apply to any on-site waterbodies or wetlands.

2. Is the planned discharge of fill exempt?

Not all fill discharges require a Section 404 permit. Examples include:

  • Conducting ongoing farming and ranching activities (such as minor drainage and harvesting);
  • Maintaining drainage ditches, dams, and levees; and
  • Building and maintaining irrigation ditches, farm and stock ponds, and farm and forest roads.

See 232.3 for the comprehensive list of discharge activities that don’t require a permit.

3. What impact will the fill discharge have?

The potential impact that your project will have on WOTUS determines the type of permit you need: general or individual.

General permits are issued for discharges that have only minimal adverse effects on WOTUS. They’re based on specific activities and typically require much less processing time, allowing projects to begin sooner. The types of general permits include:

  • Nationwide permits (authorize activities across the U.S.),
  • Regional general permits (authorize activities in a specific area), and
  • Programmatic general permits (authorize activities already regulated by existing state, local, or federal programs).

Individual permits are issued for discharges that may have significant impacts on WOTUS. They require case-by-case evaluations of each project.

When starting the Section 404 permitting process, keep these things in mind:

  • The permit requirements apply both to permanent and temporary projects, like using fills to access a work area for a limited time.
  • You can request to meet with the USACE before applying for a permit. It’s an informal meeting during which the USACE offers guidance and insights that could help reduce your application’s processing time.
  • Check with the state to identify any state-level permitting requirements.

Key to remember: If a project’s discharges of fill material could impact the waters of the United States, it may require a Section 404 permit under the Clean Water Act.

The next 5: EPA's latest step in chemical risk evaluations
2024-12-31T06:00:00Z

The next 5: EPA's latest step in chemical risk evaluations

Are the chemicals in your home and workplace safe? The Environmental Protection Agency (EPA) is working to answer this question with the recent launch of risk evaluations for five chemicals under the Toxic Substances Control Act (TSCA):

  • Acetaldehyde,
  • Acrylonitrile,
  • Benzenamine,
  • 4,4’-methylene bis(2-chloroaniline) (MBOCA), and
  • Vinyl chloride.

EPA selected the chemicals through a rigorous process (under TSCA section 6(b)(1)(A)) that considers potential hazards, exposure levels, and other relevant factors. A critical component of this process is the prioritization of chemicals for risk evaluation.

The prioritization process is the cornerstone of EPA's TSCA implementation. It ensures that the agency's resources are directed toward chemicals with the greatest potential to cause harm. This systematic approach allows the agency to efficiently evaluate a vast number of existing chemicals and make informed decisions about their safety.

Prioritizing existing chemicals under TSCA can include up to seven stages:

  1. Approach to prioritization EPA selects a prioritization approach that’s appropriate for the purposes of the evaluation.
  2. Candidate selection In this stage, EPA identifies potential candidates for prioritization using a variety of sources, including industry reports, scientific studies, and public input.
  3. Initiation Once the agency selects a candidate chemical, it initiates the prioritization process by gathering relevant information on the chemical's hazards, exposures, and potential risks.
  4. Screening review During this stage, EPA conducts a screening-level risk assessment to evaluate the potential risks of the chemical.
  5. Proposed designation Based on the screening review, the agency proposes a designation for the chemical as either high- or low-priority for further evaluation. Chemicals designated as High-Priority Substances enter the TSCA risk evaluation process.
  6. Final designation After considering public comments, EPA finalizes the chemical’s designation.
  7. Revision of designation EPA may revise the designation of a low-priority substance as high-priority if new information suggests that the chemical may present an unreasonable risk of injury to health or the environment.

Risk evaluation: Assessing unreasonable risks

Following prioritization, EPA immediately starts risk evaluations for chemicals designated as High-Priority Substances. The evaluations involve a comprehensive assessment of potential hazards, exposure pathways, and potential risks to human health and the environment. The goal is to determine whether a chemical presents an "unreasonable risk of injury to health or the environment."

If a risk evaluation identifies an unreasonable risk, EPA can take various regulatory actions under TSCA. These actions may include restrictions on the use, manufacture, or distribution of the chemical. The agency tailors the regulatory approach to the unique characteristics and risks of each chemical.

Key to remember: EPA recently announced the initiation of risk evaluations for five chemicals under TSCA. The chemicals were selected through a rigorous prioritization process that considers potential hazards, exposure levels, and other relevant factors.

Agency adds new temporary hazardous waste storage, transfer codes
2024-12-30T06:00:00Z

Agency adds new temporary hazardous waste storage, transfer codes

The Environmental Protection Agency (EPA) has added new Management Method Codes to describe how hazardous waste will be managed after temporary storage and transfer. The codes are used for Biennial Hazardous Waste Reports and e-Manifests required by the Resource Conservation and Recovery Act (RCRA).

What are the changes?

The new “S Codes” are effective as of January 1, 2025. The S Codes will ultimately replace code H141 for Storage and Transfer for the RCRA Biennial Reports and e-Manifests. EPA will remove Code H141 from the Biennial Report and e-Manifest on January 1, 2027.

Hazardous waste handlers will use the S Codes on the Biennial Report Waste Generation and Management (GM) forms. The S Codes indicate that (a) hazardous waste was received to be stored or transferred and (b) the hazardous waste will later be managed by a final receiving facility using a specific method.

What are the new codes?

The new Management Method Codes include the following:

S CodeDescription
S010Stored and transferred for metals recovery
S011Stored and transferred for mercury recovery
S015Stored and transferred for deployment/deactivation of airbag waste
S020Stored and transferred for solvents recovery
S039Stored and transferred for other recovery or reclamation for reuse
S040Stored and transferred for incineration
S041Stored and transferred for open burning/open detonation
S042Stored and transferred for thermal desorption
S070Stored and transferred for chemical treatment
S081Stored and transferred for biological treatment
S090Stored and transferred for polymerization
S100Stored and transferred for physical treatment only
S110Stored and transferred for stabilization
S113Stored and transferred for stabilization to remove HW characteristics or to achieve delisting levels
S120Stored and transferred for comb. of chemical, biological, and/or physical TRT
S121Stored and transferred for neutralization only
S122Stored and transferred for evaporation
S129Stored and transferred for other treatment
S130Stored and transferred for surface impoundment that will be closed as landfill
S131Stored and transferred for land treatment or application
S132Stored and transferred for landfill (with prior treatment and/or stabilization)
S134Stored and transferred for deepwell or underground injection

When do the new codes apply?

Handlers may use the new S Codes on the 2025 Biennial Report GM form, on the 2026 Annual Report in some states, and for e-Manifests. While handlers may continue using code H141, EPA recommends shifting to S Codes before January 1, 2027, when code H141 will be removed.

Key to remember: EPA’s new S Codes for Biennial Reports and e-Manifests indicate how the final receiving facility will manage temporarily stored and transferred hazardous waste.

New chemical review: What are the 5 possible results?

New chemical review: What are the 5 possible results?

Before a new chemical substance can enter the marketplace, it first travels through the New Chemicals Review Program. Section 5 of the Toxic Substances Control Act (TSCA) requires the Environmental Protection Agency (EPA) to review new chemicals for any unreasonable risk of injury they may pose to human or environmental health. The agency determines (a) whether the substances can enter the marketplace and (b) if they require restrictions to manage any unreasonable risk.

To manufacture (including import) a chemical for commercial purposes that’s not on the TSCA Chemical Substance Inventory (i.e., a new chemical), you have to submit a premanufacture notice (PMN) to EPA. In December 2024, EPA finalized the new chemicals review rule. It clarifies that when you submit a PMN, you may not manufacture the new chemical substance until the agency issues a safety determination and completes any associated actions (like developing rules to limit its use).

Start the PMN process by conducting your own review! Evaluate and prepare for the possible determinations EPA will make for your new chemical substance.

Safety determinations

Submitting a PMN sparks the beginning of the new chemicals review process. EPA completes the review process by making one of five possible safety determinations for the new chemical.

It’s important to note that three types of determinations fall under the scope of Section 5(e) actions. If EPA makes any determination under Section 5(e), it must issue a Section 5(e) order with requirements that limit or ban the manufacture, processing, distribution in commerce, use, or disposal of the new chemical. Examples include toxicity testing, personal protective equipment for exposed workers, and environmental release restrictions.

Let’s take a look at each one.

Section 5(a)(3)(C): Not likely to present an unreasonable risk

In the most straightforward scenario, EPA can find that the new chemical isn’t likely to pose an unreasonable risk.

In this case, the agency will notify you and publish its findings in the Federal Register. Once you receive the Section 5(a)(3)(C) notice from EPA, you may begin manufacturing the new chemical substance, even if the applicable review period isn’t over.

Section 5(f): Presents an unreasonable risk

The agency may find that a new chemical presents an unreasonable risk of injury.

It will use Section 5(f) to limit or ban the manufacture, processing, distribution in commerce, use, or disposal of the new chemical through either:

  • A proposed rule that takes immediate effect, or
  • An issued order.

Section 5(e): Insufficient information

The agency may determine that it doesn’t have enough information to make a “reasoned evaluation” of the new chemical’s impact on health and the environment.

EPA will issue a Section 5(e) order with restrictions to mitigate or eliminate the unreasonable risk.

Section 5(e): May present an unreasonable risk

If EPA doesn’t have enough information, it can alternatively determine that the new chemical poses an unreasonable risk due to insufficient information.

The agency will issue a Section 5(e) order with restrictions to mitigate or eliminate the unreasonable risk.

Section 5(e): Presents unreasonable risk due to quantity

On the other hand, EPA may determine that the new chemical will be produced in substantial quantities that could (a) be released in large amounts to the environment or (b) result in significant human exposure.

EPA will issue a Section 5(e) order with restrictions to mitigate or eliminate the unreasonable risk.

Regulatory action

In December 2024, EPA finalized changes to the rule for new chemical reviews. It clarifies that the agency must make one of five statutory determinations for each PMN, significant new use notice, and microbial commercial activity notice it receives.

The final rule also:

  • Eliminates full review exemptions for per- and polyfluoroalkyl substances (or PFAS) as well as for persistent, bioaccumulative, and toxic (PBT) chemicals if environmental releases of or potentially unreasonable exposures to PBT chemicals are expected;
  • Clarifies the information required in new chemical notices;
  • Changes EPA’s procedures for reviewing notices with incomplete information or errors;
  • Updates the application form on the EPA Central Data Exchange; and
  • Streamlines the suspension request process for submitters.

Key to remember: EPA reviews each new chemical and makes one of five possible safety determinations that dictate both if and how the substance can enter the marketplace.

Chemical management: Minimizing risks, maximizing compliance
2024-12-10T06:00:00Z

Chemical management: Minimizing risks, maximizing compliance

In 2022, the National Institute for Occupational Safety and Health (NIOSH) reported a staggering 658,000 workers were exposed to harmful chemicals, resulting in 839 fatalities. These statistics highlight the significant health and safety risks that an unexpected exposure to a hazardous chemical, or a substantial threat of a hazardous substance release, can pose to workers, organizations, and communities. A thorough understanding of chemical management regulations is crucial to ensure potential hazardous exposures are minimized.

Hazard communication (HazCom)

OSHA’s HazCom standard (29 CFR 1910.1200) is designed to inform workers about chemical hazards and how to protect themselves.

Key definitions: A "hazardous chemical" is any chemical which is classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, or other hazards not that may not be classified but still pose a serious danger.

Indicators: Any workplace where hazardous chemicals are used, stored, or processed needs a hazard communication program. Labels, safety data sheets (SDSs), and employee training are essential components.

Training requirements: Training must cover how to read and understand labels, the purpose and location of SDSs, and specific protective measures when handling hazardous chemicals. Training must be provided upon initial assignment and updated whenever new chemical hazards are introduced.

Hazardous materials (Hazmat)

The DOT’s hazmat regulations (DOT 49 CFR Parts 171-180) include substances that, if transported improperly, can harm people, property, or the environment. By correctly handling and moving these materials, organizations can avoid accidents and safeguard both public health and the environment.

Key definitions: A "hazardous material" is any substance or material capable of posing an unreasonable risk when transported in commerce. This can include flammable, toxic, and reactive substances.

Indicators: Activities involving the loading, unloading, and handling of hazardous materials require adherence to hazmat regulations. This requirement also applies to organizations that make or maintain packaging, or a part of packaging, that's marked or sold as suitable for transporting hazardous materials commercially.

Training requirements: Workers handling hazmat must undergo specific training on material classification, safe handling, emergency response, and transportation. Training must be provided within 90 days of initial assignment and a refresher at least once every three years. Training must also be documented and retained for a minimum of three years.

Hazardous waste (Hazwaste)

The EPA’s hazwaste regulations (40 CFR Parts 260-299) refer to any waste material that could potentially harm the environment or human health if not managed correctly. Additionally, many states have hazardous waste requirements beyond EPA regulations.

Key Definitions: Hazardous waste includes materials classified as toxic, ignitable, corrosive, or reactive, based on specific criteria.

Indicators: Managing hazardous waste follows the material’s entire lifecycle including the generation, transportation, treatment, storage, and disposal, known as "cradle-to-grave." Requirements are based on the quantity of waste generated.

Training requirements: Employees involved in hazardous waste management must receive training on waste handling, storage, labeling, and disposal procedures. Annual training requirements are based on generator quantity status.

Hazardous waste operations and emergency response (HAZWOPER)

OSHA’s HAZWOPER standard (29 CFR 1910.120) protects workers involved in hazardous waste management and emergency response. HAZWOPER covers a wide range of activities, including cleanup operations and responses to hazardous substance releases.

Key definitions: A hazardous substance is any material that can harm health and safety if released into the environment. In the context of HAZWOPER, this includes materials that pose risks in emergencies, such as spills, leaks, or other uncontrolled releases.

Indicators: Workers and organizations tasked with hazardous waste cleanup, spill response, and emergency operations require specialized training, equipment, and procedures.

Training requirements: HAZWOPER training is intensive and includes specific requirements depending on job roles. Training levels include 24-hour, 40-hour, and 8-hour refresher courses for different exposure risks. Employees learn about hazardous substance properties, emergency response procedures, PPE use, and decontamination processes.

Process Safety Management (PSM)

OSHA’s PSM standard (29 CFR 1910.119) aims to prevent accidental chemical releases that could seriously harm employees or the environment by including safety measures, risk assessments, and employee training to ensure safe operations. It is especially important in industries handling highly hazardous chemicals including facilities with high-risk chemical processes.

Key definitions: OSHA defines a "highly hazardous chemical" as any substance that poses a significant risk of causing serious harm to people, property, or the environment due to its toxic, reactive, flammable, or explosive properties.

Indicators: Any workplace handling large volumes of hazardous chemicals or using complex chemical processes including chemicals that are specifically listed by OSHA in appendix A of the standard, are present in quantities above specified thresholds, or exhibit properties that make them likely to cause a major incident.

Training requirements: PSM training covers safe operating procedures, hazard analysis, and incident investigation for employees involved in high-risk processes. Training must be provided at initial assignment and a refresher at least once every three years.

Key to remember: Chemical management is a complex task. Understanding what regulatory requirements apply will ensure compliance as well as minimize the chance for dangerous incidents.

Deadliest chemical disaster still haunts, decades later

Deadliest chemical disaster still haunts, decades later

December 2024 marks the 40th anniversary of one of history’s worst industrial incidents — the release of a deadly gas at a chemical plant in Bhopal, India. This incident, along with another in West Virginia in 1985, spurred U.S. legislative and regulatory action. However, some might say that work is not finished.

Think of the Emergency Planning and Community Right-to-Know Act (EPCRA) of 1986, the EPA Risk Management Program (RMP) standard, and the OSHA Process Safety Management (PSM) standard, for example. You’ll find roots to the Bhopal disaster.

What happened in Bhopal?

It was late on December 2, 1984, at a chemical facility. A faulty valve leaked water into a tank of methyl isocyanate (or MIC). This prompted a violent reaction inside the tank. History tells us that at about 1:00 a.m. on that fateful December 3, the failure of a safety valve triggered a massive release. A dense, lethal cloud of MIC and other chemicals drifted over the city of Bhopal.

By dawn, thousands of residents were dead, along with birds, dogs, cows, and other animals. The injured flocked to hospitals in overwhelming numbers. A lack of information about just what the chemicals were, however, compounded the catastrophe.

India officials reported half a million or more chemical exposures. Estimates vary, but as many as 10,000 people perished in the initial few days. Tens of thousands died prematurely in the decades to follow, according to sources.

What happened in West Virginia?

In August 1985, a chemical release in Institute, West Virginia, showed Americans that a “Bhopal-like” incident could happen here. Aldicarb oxime and other chemicals released from the facility, and over 125 residents landed in the hospital. Again, a lack of available chemical information was noteworthy. Many U.S. citizens began to fear they faced catastrophic risks.

What happened next?

In the wake of the incidents, Congress enacted laws:

Together, they required EPA and OSHA to issue regulations to:

  • Increase community chemical emergency preparedness,
  • Require companies to report worst-case release scenarios,
  • Require companies to develop RMPs and PSM programs to protect communities and workers, respectively.

Congress also established the Chemical Safety and Hazard Investigation Board (CSB) to investigate chemical incidents and recommend measures to prevent them. Despite these actions, the U.S. continues to experience serious chemical incidents. A visit to the CSB or National Response Center (NRC) websites reveals countless incident reports since 1990. A look at the 2024 data finds:

CSB video

Ten years ago, on the 30th anniversary of the Bhopal disaster, CSB posted a six-minute video explaining how the tragedy occurred. The video also examines more recent U.S. incidents. It emphasizes what more could be done to prevent similar incidents.

CSB investigations around the time of the video found deficiencies in design and PSM, similar to those uncovered in Bhopal! CSB Chairperson Rafael Moure-Eraso argued: “Process safety management regulations are in need of reform. There must be more emphasis on preventing the occurrence of major chemical accidents through safer design. Responding to emergencies and punishing people after the fact are not enough.”

Push for regulatory reform

Another headline-making incident in April 2013 involved a massive explosion of ammonium nitrate at a fertilizer storage/distribution facility in West, Texas. It fatally injured 12 volunteer firefighters and two members of the public and caused hundreds of injuries. The incident prompted the Executive Order on Improving Chemical Facility Safety and Security (EO 13650) on August 1, 2013. The order directed the federal government to:

  • Improve operational coordination with state and local partners;
  • Enhance federal agency coordination and information sharing;
  • Modernize policies, regulations, and standards; and
  • Work with stakeholders to identify best practices.

The feds held listening sessions and issued a flurry of fact sheets, alerts, and enforcement policy changes (See here and here.). Note that the RMP regulation at 40 CFR 68 was eventually amended this year on March 11, 2024. The PSM standard remains unchanged, despite a request for information on December 9, 2013. In an about-face, Congress allowed the Chemical Facility Anti-Terrorism Standards program (at 6 CFR 27) to expire on July 28, 2023, but many in Congress and industry would like to see its return.

Key to remember

This month marks the 40th anniversary of the Bhopal chemical disaster. It sparked the U.S. Congress to take steps back then to prevent such a disaster from occurring here. Those actions did not spell the end to all chemical disasters in the U.S. In response, a renewed push for regulatory reforms popped up in the last decade.

5 key release detection requirements for underground storage tanks

5 key release detection requirements for underground storage tanks

Leak detection on an underground tank storing petroleum or other hazardous materials can be the factor that prevents a release from turning into a contamination catastrophe. A leak (or release) detection system alerts tank operators and owners of potential releases, allowing them to respond and limit contamination quickly.

The Environmental Protection Agency (EPA) requires regulated underground storage tanks (USTs) to have release detection systems. Here are five things you should know about complying with UST leak detection requirements.

1. The rules cover the entire UST system.

EPA’s release detection requirements (40 CFR Part 280 Subpart D) apply to USTs and any underground piping connected to the tanks.

Owners and operators must equip each regulated UST and piping with leak detection that:

  • Detects a release from any part of the tank or its piping that routinely contains petroleum or hazardous waste;
  • Meets the manufacturer’s instructions for proper installation and calibration;
  • Follows the operation, maintenance, and testing requirements of the manufacturer’s instructions, a nationally recognized code of practice, or the implementing agency; and
  • Complies with federal performance standards.

2. Tank release detection methods depend on the installation or replacement date.

The UST’s date of installation or replacement determines the release detection methods that owners and operators can use for the tank. There are three categories of release detection methods:

  • Interstitial (e.g., secondary containment with interstitial monitoring),
  • Internal (e.g., automatic tank gauging systems), and
  • External (e.g., groundwater monitoring).

Owners and operators of USTs installed on or before April 11, 2016, choose at least one leak detection method from the range of interstitial, internal, and external options (or another method approved by the implementing agency). However, owners and operators of USTs installed or replaced after April 11, 2016, must use secondary containment with interstitial monitoring.

3. Piping release detection methods depend on two factors.

The release detection methods for piping that UST owners and operators can use are based on (a) the date of installation or replacement and (b) the type of piping.

Pressurized piping installed on or before April 11, 2016, must:

  • Have an automatic line leak detector that shuts off or restricts product flow or triggers an alarm, and
  • Receive annual line testing or monthly monitoring.

Pressurized piping installed or replaced after April 11, 2016, must also have an automatic line leak detector and use secondary containment with interstitial monitoring.

Suction piping installed on or before April 11, 2016, must use monthly monitoring or line testing every three years (unless the piping is exempt from requirements). Suction piping installed or replaced after April 11, 2016, must use secondary containment with interstitial monitoring (unless the piping is exempt from requirements).

4. Secondary containment with interstitial monitoring is the standard.

EPA revised the UST regulations in 2015, requiring all new and replaced tanks and piping to use secondary containment with interstitial monitoring for release detection. For example, say you have a UST installed before April 11, 2016, but you have to replace its piping. You must use secondary containment with interstitial monitoring for the replaced piping.

Secondary containment refers to a physical barrier between the UST and the environment, such as a double-walled tank or internally fitted liner. If the UST leaks, the barrier holds the leak between the tank and the barrier so it can be detected.

The interstitial monitor detects leaks between the tank and the barrier and alerts owners and operators of a potential leak. Monitoring devices range from physical dipsticks to high-tech pressure and liquid-detecting sensors.

5. State requirements may differ.

Many states implement the UST regulatory program. State requirements must be at least equal to EPA’s, and in some cases, they may be more stringent.

Whether you have one UST at a facility or several at facilities across the country, it’s vital to check state requirements to ensure you comply with all applicable standards.

UST release detection systems can help your facility prevent potential leaks from turning into environmental — and compliance — disasters.

Key to remember: EPA requires underground storage tanks to have release detection systems that alert owners and operators quickly to potential leaks.

EPA airs interim Good Neighbor Plan rules for power plants and industrial facilities
2024-11-13T06:00:00Z

EPA airs interim Good Neighbor Plan rules for power plants and industrial facilities

Future emission requirements for certain power plants and other industrial sources across 23 states remain up in the air. The Environmental Protection Agency (EPA) published the Third Final Interim Rule for its Good Neighbor Plan (GNP) in October 2024, officially pausing the federal emissions-control program in all affected states as legal battles continue.

So, the GNP requirements are paused, but what does that mean for the facilities covered by the rule?

What’s the GNP rule? Who does it impact?

The GNP is a federal program for 23 states that requires fossil fuel-fired power plants and other industrial facilities (such as manufacturers and solid waste incinerators) to lower emissions of ozone-forming nitrogen oxides (NOx) that hinder downwind states’ ability to achieve and maintain the 2015 Ozone National Ambient Air Quality Standards (NAAQS).

Interim GNP rules set

EPA issued the First and Second Interim Final Rules in 2023 in response to a judicial order to partially stay the agency’s disapproval of State Implementation Plans (SIPs) for implementing the NAAQS. The rules temporarily stopped enforcement of the GNP in 12 states.

In July 2024, the U.S. Supreme Court issued an order of stay for three other states challenging the GNP rule in a separate case. EPA responded to the Supreme Court with the Third Interim Final Rule. Although the Supreme Court’s order addresses only the states involved in the case, the rule pauses the GNP’s requirements for the emissions sources in all remaining 11 states.

Interim rule requirements

Until the GNP rule is settled, power plants and industrial facilities must meet the less stringent 2008 Ozone NAAQS. Two rules address interstate emissions for this standard:

  • The 2016 Cross-State Air Pollution Rule Update for the 2008 Ozone NAAQS (CSAPR), and
  • The 2021 Revised CSAPR.

Power plants

For the interim, power plants in states with previous interstate air pollution requirements for the 2008 Ozone NAAQS are subject to equivalent requirements established by the CSAPR and Revised CSAPR rules:

  • Power plants covered by the CSAPR’s NOx Ozone Season “Group 2” Trading Program before the GNP remain subject to the state emissions budgets and unit-level allowances set in the CSAPR. These include power plants in Alabama, Arkansas, Mississippi, Missouri, Oklahoma, and Texas. Further, power plants in Wisconsin transfer back to the Group 2 trading program.
  • Power plants covered by the Revised CSAPR’s NOx Ozone Season “Group 3” Trading Program before the GNP transfer back to the Group 2 trading program. However, the emissions budgets and unit-level allowances set in the Revised CSAPR’s Group 3 trading program apply. These affect power plants in Kentucky, Louisiana, and West Virginia.
  • Other power plants covered by the Revised CSAPR’s NOx Ozone Season “Group 3” Trading Program before the GNP transfer to the Group 2 trading program. But, the emissions budgets and unit-level allowances set in the Revised CSAPR’s Group 3 trading program apply.

The interim rules also make allowances interchangeable for power plants in some states for Group 2 trading program compliance, including Illinois, Indiana, Kentucky, Louisiana, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Virginia, and West Virginia.

Power plants in Alabama, Arkansas, Mississippi, Missouri, Oklahoma, and Texas retain their banked Group 2 allowances. Also, Kentucky, Louisiana, and West Virginia may convert banked 2021–22 Group 3 allowances to Group 2 allowances.

Power plants in Illinois, Indiana, Maryland, Michigan, New Jersey, New York, Ohio, Pennsylvania, Virginia, and Wisconsin may convert their 2021–23 Group 3 allowances to Group 2 allowances. However, EPA will recall the 2024 Group 3 allowances issued before the stay order.

Power plants in Minnesota, Nevada, and Utah weren’t covered by previous ozone NAAQS requirements, so they maintain the status quo. Additionally, California power plants aren’t subject to GNP requirements.

Industrial sources

Most of the GNP’s requirements for industrial facilities don’t begin until the start of the 2026 ozone season (May 1, 2026). EPA won’t enforce the deadlines that occur before then for procedural requirements, such as submitting optional case-by-case emissions limits requests.

What’s the future of the GNP?

For now, the future of the GNP remains unclear due to ongoing litigation. EPA’s administrative stay remains in effect until:

  • The U.S. Supreme Court lifts its stay order,
  • Other courts lift judicial stay orders for SIP disapprovals, and
  • EPA establishes rulemaking aligned with any judicial rulings on the merits of the GNP.

Plus, if a state’s judicial stay order due to SIP disapproval is lifted, the agency won’t remove the stay for the state’s emissions sources until the Supreme Court lifts its stay order.

Key to remember: EPA’s final interim rules establish temporary compliance requirements for power plants and other industrial sources while the Good Neighbor Plan remains paused.
