EEC Environmental (EEC) formulated a compliance strategy for stormwater management for a major international defense system manufacturer, located at the company’s production facility in the Baltimore area. Based on the nature of the facility’s operations, EEC pursued a strategy to demonstrate that there could be no potential for exposure of any pollutants to stormwater discharged from the property. In such case, the facility would be excluded from stormwater permitting requirements.

To implement this strategy, EEC professionals conducted a detailed assessment of stormwater runoff and stormwater management practices at the Baltimore facility. EEC performed a detailed inspection of the property, including the stormwater drainage system, the manufacturing process, and the facility perimeter. In addition, EEC professionals reviewed all applicable water and waste management procedures to ensure that materials from the manufacturing and materials handling processes could not come in contact with stormwater.

Based on the client’s ability to prevent stormwater contamination from hazardous substances in use at their facility, EEC was able to obtain an exclusion from the stormwater monitoring requirements of the State of Maryland under the state’s General Permit for Discharges from Stormwater Associated with Industrial Activities.

EEC’s Stormwater/ National Pollutant Discharge Elimination System (NPDES) group has developed and implemented municipal, industrial, commercial, and construction programs to achieve full compliance with federal, state, and local stormwater regulations. EEC has been specializing in stormwater compliance for more than 20 years. Our staff has assisted both Municipal Separate Storm and Sewer Systems (MS4) programs and industrial facilities with compliance issues as part of these services. EEC develops Local Implementation Plans (LIPs) that include program management and the inventory, prioritization, and inspection of industrial, commercial, and municipal facilities.
