People whose construction activity disturbs an area 1 acre or greater in size are required to obtain a permit authorizing the activity. The permit is issued by the Colorado Department of Public Health and Environment (CDPHE). Before July 1, 2002, a permit wasn't needed if the construction activity was under five acres. The 5-acre threshold has been in effect for several years.
Aside from clearing, grading and excavation activities, disturbed areas also include areas receiving overburden (e.g., stockpiles), and areas with heavy equipment/vehicle traffic and storage. The new permit requires that a stormwater management plan be developed before the activity begins.
Application forms and information about how to design a stormwater management plan are available from the CDPHE, or you can contact them at (303) 692-3517.
This process for protecting water quality is part of a larger three-phase program called the National Pollutant Discharge Elimination System (NPDES). The five-acre threshold was part of Phase 1 regulations, the new one-acre threshold is part of Phase 2 regulations.
