The USACE Philadelphia District is seeking capable small businesses to provide stormwater sampling and monitoring services for nine facilities across Maryland, Massachusetts, New Hampshire, New York, and Pennsylvania. The 99th Readiness Division requires professional technical support to ensure compliance with state and federal stormwater permits, as they lack in-house expertise. Services include analytical sampling, monitoring, and reporting to regulatory agencies such as the MDE, EPA, NYSDEC, and PADEP. The contractor may use representative outfalls for sampling where applicable, after verifying the conditions. No specific budget amounts or performance timelines are mentioned in the description.
