Operators of most construction activities within Doña Ana County are required to prepare a Storm Water Pollution Prevention Plan (SWPPP). This is the same SWPPP which the Environmental Protection Agency requires for construction activity. The SWPPP must be submitted to the County for review a minimum of 30 days before disturbing any land. For Subdivisions, the SWPPP must be included with the Final Subdivision Plan submittal. The SWPPP requirements are in Section 9 of the County’s Storm Water Management Ordinance.

To determine if your construction activity needs a SWPPP: SWPPP Flow Chart

To determine if your construction activity qualifies for a Low Erosivity Waiver (LEW) from the SWPPP requirement: LEW Flow Chart

The construction activity may also be required to submit a Notice of Intent to the EPA. For more information on EPA’s permit and requirements for construction activity: http://cfpub.epa.gov/npdes/stormwater/const.cfm
