Field
NM
New Mexico
NPDES ProgramState-Delegated
Permitting AgencyNew Mexico Environment Department (NMED)
Permit NameNPDES/NMPDES General Permit for Stormwater Discharges from Construction Activities (Permit No. NMR10A000)
Construction Threshold≥ 1 acre of land disturbance, or < 1 acre if part of a larger common plan of development or sale that will ultimately disturb ≥ 1 acre. Sites < 1 acre not part of a larger plan are regulated by NMED on a case-by-case basis if they discharge to waters of New Mexico.
NOI Lead TimeA Notice of Intent (NOI) must be submitted to NMED at least 2 business days before land disturbance begins and before the discharge commences. The 2-day lead time is notably shorter than most states. NMED acknowledges coverage; operators should confirm receipt before disturbing land.
Application MethodOnline submission via NMED's Environmental Bureau of Information Services (EBIS) online portal, or paper NOI mailed to NMED Ground and Surface Water Protection Bureau in Santa Fe. Online submission is preferred. A SWPPP must be completed before the NOI is filed.
Permit FeeNo permit fee for the NPDES/NMPDES construction general permit at the state level under current NMED rules. However, if an individual permit is required (rather than general permit coverage), fees apply based on NMED's fee schedule.
SWPPP RequiredYes
PE Certification RequiredNo
SWPPP Template AvailableYes
Inspection FrequencyAt least every 14 days and within 24 hours of a precipitation event producing ≥ 0.5 inches of rainfall. In arid areas of NM where rainfall is infrequent, inspections must still occur every 14 days during the active construction period. Inspection reports must be retained as part of the SWPPP record.
Inspector QualificationNo state-specific certification is required by the general permit. Inspectors must be knowledgeable individuals familiar with the SWPPP and BMP requirements. NMED does not currently mandate a specific credential such as CPESC or a state-issued inspector license. The operator or their designee may conduct inspections.
Post-Construction RequiredYes
Turbidity StandardNo numeric NTU turbidity limit specified in NMR10A000; narrative water quality standards apply.
