CCR Sampling and Analysis Plan Development, Groundwater Sampling and Unlined Surface Impoundment Closure Support

KEMRON developed a comprehensive Groundwater Sampling and Chemical Analysis Plan (SAP) for multiple coal-burning generation facilities in the Midwest. This plan aimed to ensure consistent sampling and analysis procedures that protect human health, safety, and the environment, providing accurate representations of groundwater quality. The plan was designed in accordance with the EPA’s Coal Combustion Residuals (CCR) Rule.

Following the development and approval of the SAP, KEMRON conducted initial groundwater sampling to meet the requirements of the Federal CCR Rule at 40 CFR 257.93 (a) through (c). This initial phase involved collecting eight discreet samples from monitoring wells in the PE-certified groundwater monitoring networks around inactive fly ash ponds, permitted CCR receiving landfills, and bottom ash process ponds. Parameters from 40 CFR Part 257 Appendix III (Constituents for Detection Monitoring) and Appendix IV (Constituents for Assessment Monitoring) were collected during this phase to establish baseline data.

Continuing monitoring is being conducted at various units for state permit compliance and federal CCR (detection and assessment) monitoring, following the collection of initial background data. KEMRON’s ongoing efforts ensure that the monitoring programs remain compliant with regulatory requirements and continue to protect environmental and public health.

In support of the closure of unlined CCR surface impoundments, KEMRON provided dewatering treatment monitoring services to comply with the EPA CCR Part A Final Rule, effective August 28, 2020. This monitoring involved sample collection and data trending to demonstrate system efficiency and ensure compliance with facility NPDES discharge and process requirements.

KEMRON employed various groundwater sampling techniques, including low flow, snap samplers, three well volume purge and sample, and passive diffusion samplers. Field techniques for water quality monitoring and field analysis were also utilized to ensure the highest accuracy in data collection.

The project adhered to multiple regulatory frameworks, including the CCR Rule, state landfill permits, NPDES, and the Clean Water Act. KEMRON’s methodical approach ensured compliance with all relevant regulations, maintaining environmental integrity and public safety throughout the project.
