A Review of the Hollis Stormwater Management Ordinance Todd H. Dresser, CHMM Cuoco & Cormier Engineering Associates
Regulatory History of Stormwater Management: • In 1992, Phase I of the National Pollutant Discharge Elimination System enacted under the federal Clean Water Act. • NPDES establishes stormwater permitting & treatment standards. • Applies to: 1) construction sites involving 5+ acres, 2) certain industrial activities, and 3) large municipalities.
Phase I Requirements: • Regulated entities must complete the following: • File Notice of Intent with EPA to obtain a discharge permit. • Prepare a Stormwater Pollution Prevention Plan (SWPPP). • Conduct routine site inspections.
Phase II of NPDES Implemented in March 2003 • Significantly increases the number & types of facilities covered by federal stormwater regulations. • The following activities are now regulated: • Construction disturbing 1 acre. • More manufacturing/industrial facilities. • All municipal drainage systems within ‘Urbanized Areas’.
The Meaning of Phase II • Regulated municipalities are required to: • Provide public education. • Seek public participation. • Locate & eliminate illicit discharges. • Establish stormwater controls for construction. • Establish post construction stormwater controls. • Initiate good housekeeping & pollution prevention practices at municipal facilities.
Proposed Ordinance Mirrors Existing Federal Requirements • Regulated developers & industrial facilities would be required to submit copies of NOI’s, SWPPP’s & inspection reports required by Phase I & II to the Town. • The ordinance enables the community to investigate & address drainage problems that if left unabated could create liability concerns for the town.
Local Modifications to the Regulations • The regulated entities are required to submit all NPDES records to the Town. • Industrial facilities would be required to conduct quarterly inspections instead of semi-annual inspections. • The regulation grants the Town the authority to take action against failing drainage systems. • The ordinance applies to the entire town.
Benefits of Ordinance • Protects local aquifer & resource areas. • Enables the staff to focus attention on problem sites. • Achieves regulatory compliance.
