COAL COMBUSTION RESIDUAL (CCR) SERVICES

WET provides a wide range of services related to Coal Combustion Residual (CCR) efforts.

WET has extensive experience in all aspects of compliance with 40 CFR 257 and provides full services to facilities that are required to comply with these new Legacy regulations. WET has experts in location criteria, air monitoring, ground water monitoring, statistics, CCR compliant closure and corrective measures. Our successful track record with CCR landfills and CCR impoundments can ensure your facility is in full compliance with EPA CCR Legacy Regulations with timely, defendable, and appropriate actions.

We have experience with Coal Combustion landfills and waste impoundments dating back to 1988. As with all regulations, compliance with the details of the regulations is critical. WET prides itself on its extensive experience with location criteria, low flow groundwater monitoring, statistical analysis and corrective measures that fully meet the EPA requirements.

With professionals experienced in the original CCR regulations, we have guided multiple facilities through the process of: Beneficial Reuse, Siting Criteria, Ground Water Monitoring, Detection Monitoring, Assessment Monitoring, Assessment of Corrective Measures, Selection of Remedy, Closure criteria, Post Closure Care, Recordkeeping and notification requirements, Internet posting.

Location Restrictions (40 CFR 257.60- .65)

WET can complete the siting evaluation for facilities by determining: Placement above the uppermost aquifer, proximity to wetlands, Proximity to fault areas, Seismic Impact Zones and unstable areas. WET’s team of professionals have completed this analysis for new and existing CCR facilities.

Design and Closure Criteria (40 CFR 257.70 – .74)

WET has designed, permitted, and constructed both new impoundments and landfills and closed several facilities under compliance with the EPA and State regulations. Liner criteria and capping requirements are addressed in the design and permitting stage. Closure has been completed with the proper caps and dewatering to meet the criteria.

Ground Water Monitoring (40 CFR 257.90 – .95)

WET has a group of professional Hydrogeologist that have experience with designing a monitoring system that meets all criteria of 40 CFR 257.90-.98. This team includes Geologists, Geophysicists and Geochemists that comply characterize the facility and identify the source of impacts, whether they are naturally occurring, from an alternate source, or require Corrective Measures.

Corrective Measures (40 CFR 257.96 – .98)

WET personnel have been implementing corrective measures at CCR facilities since 1988 when the original Subtitle D regulations required Coal Fired Generator to comply with Landfill Regulations. These actions have included improved caps, dewatering of ash and FGD Waste, ground water capture systems or pump and treat technology. Detailed geophysical investigations have recently been implemented to characterize problem sites with fractured bedrock issues.

At more challenging sites, WET has installed horizontal capture wells under impoundment to remove impacts and ensure separation between waste and ground water. In addition, our geochemists have completed isotope analysis to separate naturally occurring concentrations from actual contributions from the facility.

Record Keeping, Posting, Internet Requirements (40 CFR 257.105 – .107)

WET has complied with notification and posting requirements for multiple facilities during implementation of the original CCR regulation. Our experience will ensure your facility is in compliance with all applicable Legacy regulations.

WET has successfully navigated the CCR regulations for a major Coal Fired Generation company with multiple facilities in the western US. These actions included implementation of all aspects of the regulations from location requirements through corrective measures. We have a team of professionals that understand the regulations and have direct experience complying with each step of the process and meet all the deadlines associated with each step of the process.
