The Virginia Department of Environmental Quality (DEQ) revised general permit for industrial stormwater discharges became effective on July 1, 2009. The revised permit changed the compliance requirements for many industrial sectors that are subject to the industrial storm water regulations.
Existing facilities that were previous covered under the VDEQ industrial permit are required to come into compliance with the reissued permit by October 1, 2009.
The reissued permit amended some of the requirements for benchmark monitoring, including adding some new industrial sectors that in the past had not been required to conduct benchmark (chemical) monitoring of their stormwater discharges. The amended permit also added to the number of chemical parameters some sectors need to sample for.
Newly Added industrial Sectors that require benchmark monitoring
Sector P Land Transportation and Warehousing
Sector U Dairy Products Facilities
Sector R Ship and Boat Building or Repairing Yards
Industrial Sectors with Expanded Benchmark Monitoring Requirements
Sector N - Ship Dismantling, Marine Salvaging and Marine Wrecking Facilities
Sector S - Airports
The revised permit clarified that benchmark monitoring needs be performed at least once during at least the first two, and potentially all monitoring periods, unless the facility qualifies for a waiver. Benchmark monitoring waiver requests will be evaluated by DEQ based upon (1) benchmark monitoring results below the applicable benchmark concentration values; (2) a favorable compliance history (including inspection results); and (3) no outstanding enforcement actions. The benchmark monitoring waivers can be revoked by DEQ for cause. The revised general storm water permit also clarified that for inactive and unstaffed sites must have no industrial materials or activities exposed to storm water to qualify for this waiver
