haracterize offsite groundwater users who could be affected by the degradation of aquifers. Include locations and elevations of offsite wells, pumping rates, screened intervals, depth to water, and an estimate of the groundwater needs of local users. DG-4015, Page 30 • Describe possible mitigation measures, if they are warranted, and whether they will be implemented. Groundwater and Soil Contamination This section applies to plants that may have soil or groundwater contamination due to industrial practices involving the use of solvents, hydrocarbons, heavy metals, or other chemicals. Onsite sources may include lined or unlined lagoons, pipe and valve leakages, fuel spills, or other inadvertent incidents. Table B-1 states the following: Industrial practices involving the use of solvents, hydrocarbons, heavy metals, or other chemicals and unlined wastewater lagoons have the potential to contaminate site groundwater, soil, and subsoil. Contamination is subject to State- and Environmental Protection Agency (EPA)-regulated cleanup and monitoring programs. Specifically, 10 CFR 51.53(c)(3)(ii)(O) requires the following: If the applicant’s plant conducts industrial practices involving the use of solvents, hydrocarbons, heavy metals, or other chemicals and has unlined wastewater lagoons, the applicant shall assess the potential for contamination of site groundwater, soil, and subsoil. The applicant shall provide an assessment of dissolved chemical and suspended sediment discharge to the plant's wastewater lagoons in addition to National Pollutant Discharge Elimination System (NPDES) compliance data collected for submittal to the U.S. Environmental Protection Agency (EPA) or designated State agency. A summary of existing reports describing site groundwater and soil contamination should also be included. Section 4.5.1.2 of the GEIS discusses this issue. It is possible that, for a given plant, no spills or incidents have occurred. In that case, reporting of soil and
