The Industrial Storm Water Permitting Program operates under the Delaware Regulations Governing the Control of Water Pollution (7 DE Admin. Code 7201) and the Federal regulations at 40 CFR 122.

Regulated facilities can obtain permit coverage by submitting a Notice of Intent (NOI) Form or a “No Exposure” Certification Form, or apply for an individual permit.

Acceptance of the NOI Form covers a facility under Section 9.0 (General Permit Program) and requires a facility to comply with all requirements outlined within the regulations.

Acceptance of the “No Exposure” form covers a facility under the regulations, but waives a facility from complying with the Monitoring and Storm Water Plan Requirements of the regulations. “No Exposure” means that all industrial materials and activities are protected by storm resistant shelter to prevent exposure to rain, snow, snowmelt and/or runoff.
