National Emission Standards for Hazardous Air Pollutants: Municipal Solid Waste Landfills Residual Risk and Technology Review – Final NESHAP Rule

April 7, 2020

EPA has issued a revised NESHAP standard for municipal solid waste landfills.  The new rule reflects EPA’s conclusions regarding the residual risk and technology rule, resolves confusion created when the previous rule was not updated at the same time as the landfill NSPS and updates landfill gas well head criteria for temperature.  EPA is also clarifying that the standards are applicable during periods of startup, shutdown and malfunction, and requiring electronic reporting of performance test results.

EPA Summary

This action finalizes the residual risk and technology review (RTR) conducted for the Municipal Solid Waste (MSW) Landfills source category regulated under National Emission Standards for Hazardous Air Pollutants (NESHAP) contained within 40 Code of Federal Regulations (CFR) Part 63, Subpart AAAA. Additionally, the U.S. Environmental Protection Agency (EPA) is taking final action to:

  • Correct and clarify regulatory provisions related to emissions during periods of startup, shutdown, and malfunction (SSM)
  • Revise wellhead operational standards and corrective action to improve effectiveness and provide compliance flexibility
  • Reorganize rule text to incorporate provisions from the New Source Performance Standards (NSPS) within this subpart
  • Add requirements for electronic reporting of performance test results.

The EPA is also finalizing minor changes to the MSW Landfills NSPS and Emission Guidelines (EG) and Compliance Times for MSW Landfills contained within 40 CFR Part 60, Subparts XXX and Cf. Specifically, the EPA is finalizing provisions to the most recent MSW Landfills NSPS and EG that would allow affected sources to demonstrate compliance with landfill gas control, operating, monitoring, recordkeeping, and reporting requirements by following the corresponding requirements in the MSW Landfills NESHAP. According to EPA, these final amendments will result in improved compliance and implementation of the rule and eliminate some of the confusion created by the previous version of the EPA rule.

This final rule became effective on March 26, 2020.

 

We’ve pulled this information from the Final Amendments to Air Toxics Standards for Municipal Solid Waste Landfills and SCS will publish an SCS Technical Bulletin on our blog and social media sites. Please contact your Project Manager for details specific to your operation.

Actions:

Approximately 738 MSW landfills are subject to the NESHAP.

On February 25, 2020, EPA finalized amendments to the 2003 NESHAP for MSW Landfills. EPA issued air toxics standards for the MSW Landfills source category in 2003 that established emission limitations based on maximum achievable control technology (MACT) standards for hazardous air pollutants (HAP) from major and area sources.

The rule required MSW landfills greater than 2.5 million megagrams (Mg) and 2.5 million cubic meters with uncontrolled emissions greater than 50 Mg/year of non-methane organic compounds (NMOC) to install and operate a gas collection and control system (GCCS). Most emissions from MSW landfills come from the continuous biodegredation of the MSW. Landfill gas contains methane, carbon dioxide and more than 100 different NMOC, including, but not limited to, vinyl chloride, ethyl benzene, benzene and toluene.

Based on the RTR, EPA is finalizing no changes to the existing standards because the agency determined the risks to be acceptable with an ample margin of safety to protect public health and the environment. In addition, EPA did not identify any new cost-effective emission controls for MSW landfills. However, EPA is finalizing several minor amendments to reorganize and streamline requirements for MSW landfills that will improve the clarity, compliance and implementation of the rule. These include:

  • Overall NESHAP reorganization to reduce overlapping applicability and to promote consistency with the 1996 and 2016 NSPS and EG
  • Regulatory text for the 2016 NSPS/EG that allows affected sources to demonstrate compliance with the applicable sections of the rules by “opting in” to the operating, compliance and monitoring provisions of the NESHAP
  • Revisions to the GCCS wellhead temperature operating standard and the associated procedures for enhanced monitoring
  • Requirements for submitting electronic copies of compliance reports, including performance test results
  • Updated regulatory language for periods of startup, shutdown, and malfunction to be consistent with recent court decisions and a work practice standard for the periods when the GCCS is not operating
  • Residual Risk and Technology Review

 

Background

The Clean Air Act (CAA) requires EPA to regulate toxic air pollutants, also known as air toxics, from categories of industrial facilities in two phases. The first phase is “technology-based,” where EPA develops standards for controlling the emissions of air toxics from sources in an industry group or “source category.” EPA bases these MACT standards on emission levels that are already being achieved by the best-controlled and lower-emitting sources in an industry. Within 8 years of setting the MACT standards, the CAA directs EPA to assess the remaining health risks from each source category to determine whether the MACT standards protect public health with an ample margin of safety and protect against adverse environmental effects. This second phase is a “risk-based” approach called residual risk. Here, EPA must determine whether more health-protective standards are necessary.

Every 8 years after setting MACT standards, the CAA requires EPA to review and revise the standards, if necessary, to account for improvements in air pollution controls and/or prevention and to address any residual risks that still remain after the MACT is implemented.

 

Residual Risk Assessment

The CAA requires EPA to assess the risk remaining after application of the final air toxics emission standards; known as a residual risk assessment. Based on the completed risk assessment, available health information, and associated uncertainties, EPA determined risks from the MSW Landfills source category are acceptable and provide an ample margin of safety to protect public health. EPA estimates the maximum individual lifetime cancer risk for inhalation for the source category to be less than 10-in-1 million.

 

Technology Review

The CAA requires EPA to assess, review and revise air toxics standards, as necessary, taking into account developments in practices, processes and control technologies. The technology review of the standards for MSW Landfills did not identify any developments that would further reduce HAP emissions beyond the original NESHAP.

The Who, What, When, Where, Why of an Environmental Insurance Claim

May 13, 2019

The 5Ws of Environmental Insurance

 
An environmental insurance claim is simply the response and mitigation of an environmental issue or event paid for by an environmental insurance policy. Similar to an auto or home insurance claim, a company or individual purchases this type of policy to protect them in case a matter arises about their facility, operations, or property resulting in a regulatory requirement for investigation and remediation; forming the basis for a submitted claim. Such responses cost money, often a lot of it, and the environmental insurance policy is there to pay for the costs associated with the investigation and remediation of any environmental issues.

Any environmental issue can result in an environmental claim, so it is essential that you have the right policy in place to cover a particular claim. Typical issues or events include:

  • An underground storage tank release (i.e., at a gas station),
  • Vehicle accidents (i.e., a tanker truck rollover),
  • Operational incidents (i.e., the release of a chemical at a plant or factory),
  • Fires or natural disasters (i.e., contaminant release to the air, water, or soil), and
  • Indoor air quality (i.e., asbestos and mold).
The onus is on the client to provide sufficient information to substantiate a claim, even for straightforward situations.

Insurance clients submit notice to the insurance company that an environmental issue occurred or was discovered which requires investigation and corrective action. The onus is on the client to provide sufficient information to substantiate a claim submittal. The insurance company reviews this information in their evaluation of coverage for the issue under the policy.

Insurance Support for Environmental Claims

When a new claim is submitted to the insurance company, the client must provide information that substantiates that an issue exists and that further investigation and corrective action is required. Often their substantiation consists of the initial technical details about the nature and extent of the environmental problem. Claims analysts generally have a strong legal background but may lack technical environmental expertise; this is when insurance support services become valuable. The following paragraphs summarize each step in the process and how SCS insurance support assists claims analysts through the process.

Coverage Determination

Once the insurance company receives a notice of claim, they determine whether the client’s policy provides coverage for the specific issue or event that constitutes the claim. A claims analyst evaluates the specifics of the claim to determine if the associated details and circumstances fall within the specifics of the client’s policy. If so, coverage is usually accepted. If not, coverage is generally denied.

SCS’s role is to provide an evaluation of the technical aspects of the claim so that the claims analyst can take the distilled facts and compare them against the specifics of the policy; often called a “Source and Timing” evaluation. Take, for example, an underground storage tank (UST) release at a gasoline station. In this example, free product (gasoline) is observed in an on-site monitoring well where no free product has previously or recently been identified.

SCS reports provide valuable details strategic to the evaluation of a claim.

The station owner or their environmental consultant reports the apparent new release to the regulator, and a confirmed discharge is recorded. The property owner than notifies the insurance company of a gasoline release to the environment.

As part of the “Source and Timing” evaluation, SCS’s insurance support reviews tank system leak detection and inventory records, tank system tightness testing records, previous groundwater monitoring data, reports of any earlier releases at the facility, and any other information or data about the facility and the subject release. The goal is to identify:

  • Source (which tank, piping, dispenser, surface spill),
  • Timing (an approximate timeframe during which the release started or took place) and
  • Cause (tank system failure, tank overfill, surface spill).

If enough information is available to make these determinations, then the claims analyst compares the SCS report to the coverage specifics and exclusions included in the policy; determining if the event is covered. The claims analyst will usually try to make a coverage determination on their own if the facts are relatively straightforward, but often that is not the case, and the assistance of insurance support services is necessary.

This process can be straightforward, such as in the case of a tanker truck rollover or industrial facility chemical spill, but is often more complicated when insufficient information is available to make a source and timing determination.  In the latter case, the claims analyst issues a Reservation of Rights letter, stating that the insurer is not accepting or denying coverage at this time as the circumstances of the claim are still under evaluation and investigation.

Claims can be denied if the incident occurs before or after the policy period; if the source or type of incident are not included or are specifically excluded under the policy; or if the incident occurred because of the client’s negligence. If coverage is denied no further actions are generally necessary on the part of the insurance company. Whether a claim is accepted or denied is often more complicated than what we’ve discussed here.

Accepted Claim Handling

Removal of UST following the identification of the release source.

The claim is accepted; undoubtedly good news for the client. What happens now is that the claim becomes “Active,” requiring among other things for the claims analyst to set reserves. A reserve is an estimate of what the claim is going to cost the insurance company. Your insurance support consultant can provide a rough approximation of the estimated costs to achieve regulatory closure, which includes all expenses incurred from investigation through remediation, post-remediation monitoring and reporting.

Early in the life of a claim, these are preliminary estimates that are refined as a project progresses, often requiring the claims analyst to adjust their reserves; important to the insurance company as future reserves impact financial forecasts. Insurance support services will develop the cost-to-closure estimate based on all available information and data, as well as their professional experience on similar projects. The insurer wants the most experienced environmental consultants and engineers on the case because their estimates are more likely to be on target and identify potential regulatory issues or risks.

From the insurer’s standpoint, the primary goal is to maintain a high level of responsiveness to their clients and process requests for reimbursement against the claim. The role of your insurance support team can continue by managing quality control and evaluation of site-specific activities; ensuring that the investigation and cleanup are reasonable and appropriate given the environmental conditions at the site, all applicable regulatory requirements, and costs consistent with industry standards for recovery. The client and their environmental consultant are required to provide the insurer and the insurance support consultant documentation of the work as follows:

  • Proposals (submitted for review and approval before starting work)
  • Work plans
  • Technical reports
  • Progress reports
  • Copies of correspondence with the regulatory agency
  • Invoices supported by detailed substantiating documentation

Over the life of a claim, insurance support may correspond with the project consultant on behalf of the insurer, conduct site visits, and be asked to participate in meetings, conference calls, and mediations. The overall goal of your insurance support consultant is to assist claims analysts in closing a claim in the most time-efficient, cost-effective manner possible within all regulatory rules and guidelines.

Claim Closure

Once an active claim−environmental project has achieved regulatory closure, the claims analyst begins the administrative process of closing the claim. From SCS’s insurance support standpoint, all that remains is to obtain the appropriate documentation from the regulator confirming that the subject project is approved for closure and that no further actions are required.

Identification of equipment failure can result in the insurer pursuing subrogation.

There are other circumstances which may result in closing a claim, such as exceeding the maximum total cost that can be paid out by the policy, non-compliance with policy requirements, or new information coming to light which results in a change in coverage position by the insurer. In some cases, such as when there is a change in coverage position or the cause of the issue can be attributed to a third party equipment failure, the insurer may seek to recover costs expended from the client and third-party policies. That process, called subrogation, may require the expertise of your insurance support specialist and at times their testimony as an expert witness.

Federal Judge Rules Against EPA on the Landfill EG Lawsuit

May 10, 2019

Before the Court: EPA admits that it has failed to meet its nondiscretionary obligations to implement the Landfill Emissions Guidelines, as compelled by the CAA. The only questions before the Court were whether the Plaintiffs have standing and, if so, how long to give EPA to comply with its overdue nondiscretionary duties under the Landfill Emissions Guidelines. The Plaintiffs are the States of Illinois, Maryland, New Mexico, Oregon, Rhode Island, California, Vermont, and the Commonwealth of Pennsylvania.

Ruling: Plaintiffs have standing, and the EPA must approve existing submitted plans by September 6 and issue the federal plan by November 6.

Impact on Landfill Owners/Operators: This will create some confusion, as landfills will be working on getting revised rules in place while at the same time start complying with the old EG rule. We are already doing that with XXX sites, but this ruling adds complexity. If EPA keeps to the schedule and we have final approved revised rules by March 2020, landfills won’t have to do as much under the old rules before new ones take effect.

Stay tuned.

Improving Global Air Quality – Perspective in the A&WMA Publication for Young Professionals

April 5, 2018

This article discusses global air quality and how the collaboration between policy-makers and the scientific community can have a continued positive impact on air quality in the U.S. This collaboration has been the primary cause for the improvements observed in air quality over the past few decades.

U.S. Environmental Protection Agency (EPA) programs, such as the New Source Performance Standards (NSPS), New Source Review, and Maximum Achievable Control Technology standards, have all had a significant impact on improving air quality by lowering the ambient concentrations of NOX, VOC, CO, SOX, and PM.

Some areas, such as southern California, have committed to working toward electrifying the transportation network, implementing more stringent standards on diesel fuel sulfur content, and encouraging heavier utilization of public transportation.

Read the full article here.

Author: SCS Engineers’ Ryan Christman, M.S., is an air quality engineer and environmental management  information systems specialist with experience in the oil and gas industry and the solid waste industry.  He is just one of SCS’s outstanding Young Professionals.

Where Do the New Landfill Air Regulations Stand?

March 19, 2018

A look at the confusion stemming from regulatory uncertainty of new rules limiting air emissions from municipal solid waste landfills by David Greene, P.E., SCS Engineers – Asheville, NC.

The landfill industry continues to work with EPA Administration to get a longer-term stay to work out needed NSPS/EG rule changes. At this time, industry representatives are hopeful both these related goals can be achieved.

While the new NSPS/EG rules became effective back in 2016, the concerns with the rules raised at the time still remain unresolved. Despite this, we can expect resolution though it may take some time to fix. The fog should be lifting, yielding changes that are expected to be more workable for both the landfill industry and state/local regulators. In the meantime, stay tuned and stay informed.

Read the full article with links to the NSPS/EG update in a recently published SCS Technical Bulletin.
