TITLE OF THE REGULATIONS:
Regulations Governing Storm Water Discharges Associated with Industrial Activities
BRIEF SYNOPSIS OF THE SUBJECT, SUBSTANCE AND ISSUES:
The Department of Natural Resources and Environmental Control, Surface Water Discharges Section, is proposing to reissue the Regulations Governing Storm Water Discharges Associated with Industrial Activities. The regulations are required to be reissued once every five years, expanding the existing regulations in place to include all current federal requirements for discharges of storm water associated with industrial activities.
Two major revisions are: (1) a conditional "no exposure" exclusion that allows facilities with industrial materials and activities entirely sheltered from storm water a simplified way to comply with the permitting requirements by submitting a "No Exposure" certification form for exclusion from monitoring and storm water plan requirements in their permits; and (2) benchmark monitoring which requires facilities with a high potential to discharge a pollutant at concentrations of concern to conduct semi-annual analytical monitoring of storm water samples for comparison with benchmark monitoring concentration values used for indications of potential impairment of water quality in water bodies receiving the storm water discharge.
NOTICE OF PUBLIC COMMENT:
The Department of Natural Resources and Environmental Control will hold a public hearing on September 29th, 2005 at 6 PM in the DNREC Auditorium, 89 Kings Highway the Richardson & Robbins Building in Dover, to receive comments on proposed amendments to the Regulations Governing Storm Water Discharges Associated with Industrial Activities. Comments regarding the General Permit Program should be sent in writing to Amber Moore, Surface Water Discharges Section, Division of Water Resources, DNREC, 89 Kings Highway, Dover, DE 19901. Comments regarding construction activities should be sent in writing to Elaine Webb, Sediment and Stormwater Program, Division of Soil and Water, DNREC, 89 Kings Highway, Dover, DE 19901.
