Under EPA CGP NMR100000, stormwater inspections in New Mexico are required every 14 calendar days and within 24 hours of any storm event producing 0.25 inches or more of rainfall. Arizona AZPDES requires inspections within 24 hours of 0.50 inches or more. Missing an inspection is a permit violation.

Monsoon On-Call Protocol — July 1 to Sept 30

The North American Monsoon Season fundamentally changes inspection dynamics in New Mexico and Arizona. Convective storms can produce 0.25–2.0 inches in under 30 minutes with almost no notice. Standard scheduling tools that work in spring and fall break down entirely in July, August, and September.

Rain Gauge Monitoring
Site-installed tipping bucket rain gauges provide real-time rainfall data. Every active site gets a gauge installed before July 1.
NWS QPE Integration
National Weather Service Quantitative Precipitation Estimates are checked for every active site within 2 hours of any storm event.
24-Hour On-Call Coverage
On-call inspector availability from July 1 through September 30 for all active NM and AZ sites. Evening and weekend storm response included.
Same-Day Report Delivery
ComplianceGO reports delivered within 4 hours of inspection completion, even for after-hours storm response events.

What Inspectors Check — 11 CGP Inspection Areas

NMR100000 Part IV specifies the areas that must be evaluated during every inspection. Inspections Plus uses a structured checklist for all 11 inspection areas, with GPS-tagged photographs at each location.

1Disturbed soil areas with no active construction — check for interim stabilization
2Areas with completed final stabilization — verify cover density and integrity
3Material storage areas — containment integrity, secondary containment
4Structural BMPs (silt fence, sediment basins, check dams) — condition and capacity
5Non-structural BMPs (good housekeeping, spill prevention) — compliance status
6Waste disposal areas (concrete washout, liquid waste) — containment and overflow risk
7Equipment staging areas — fluid containment, fueling protocols
8Discharge points and outfalls — evidence of sediment or pollutant discharge
9Downstream receiving waters — evidence of sediment plume or turbidity
10Construction entrance/exit — trackout control BMP (Trackout Control mat or rock stabilized entrance)
11SWPPP posting and site signage — NOI posted, emergency contacts current

Pricing Philosophy

Inspection fees are billed per inspection — not as a monthly or annual package. This keeps pricing transparent and proportional to actual mobilization. Factors affecting inspection scope include site acreage, number of active BMPs, site complexity, and travel distance from our Albuquerque base of operations.

Monsoon on-call coverage (July 1 – September 30) is priced separately as an add-on to the standard inspection schedule. Contact us for project-specific estimates.
