4. Are perimeter controls (e.g., silt fences, wattles, berms) properly installed and maintained, effectively preventing sediment from leaving the site, with no visible evidence of sediment discharges beyond the site boundary? (CGP 2.2.3; CPP 2.1.2)
5. Are natural buffers (or equivalent sediment controls) maintained around water bodies within 50 feet of earth disturbances, and are these buffers effectively minimizing sediment discharges? (CGP 2.2.1; CPP 2.3.5)
6. Are stormwater discharges free of visible pollutants, and are there any prohibited discharges or sediment impacting waters of the state or unprotected storm drains? If so, immediately call the Environmental Incident Response Line [phone]. (CGP 1.3, 3.1; CPP 2.3.4)
7. Are velocity dissipation devices installed at outfalls, along drainage channels, or at other locations to slow down runoff and prevent erosion? (CGP 2.2.11; CPP 2.3.3)
Interior Site Inspection: (BMPs: Inlet Protection; Stockpiles and Construction Materials; Erosion Controls / Pollution Prevention Controls; Chemical
storage and Fueling Areas; Sanitation and Waste management; Concrete and Paint Washout )

9. Are soil and material stockpiles adequately protected from erosion and sediment transport using covers, silt fences, or other appropriate BMPs, and are they located away from stormwater conveyances and inlets? (CGP 2.2.5; CPP 2.1.1)
10. Are effective suppression measures, such as water spraying or mulching, implemented on exposed soil areas to prevent excessive dust generation? (CGP 2.2.6; CPP N/A)
11. Are erosion control measures (e.g., stabilization, mulching, erosion blankets) implemented effectively on slopes, disturbed areas, and other vulnerable areas, including any areas with no construction activities for 30 days (CPP 14 days)? (CGP 2.2.14; CPP 2.6.1)
12. Have any issues related to vegetation preservation, slope disturbances, topsoil management, or soil compaction been observed that could potentially impact water quality? (CGP 2.2.2, 2.2.7-2.2.9; CPP 2.5)
13. Are effective spill prevention, containment, and pollutant discharge minimization measures in place for all equipment fueling, maintenance, and washing activities? (CGP 2.3.1, 2.3.2; CPP 2.8.1)
14. Are chemical storage and hazardous waste areas properly managed with secondary containment and spill prevention measures in place, and are these areas free from spills or leaks? (CGP 2.3.3.c-d; CPP 2.8.3)
15. Are waste management practices effective, with all construction materials, debris, and waste properly stored, contained, and disposed of to prevent exposure to storm water and overflow? (CGP 2.3.3.a-b, e; CPP 2.4.3, 2.8.2)
16. Are portable sanitation facilities (e.g., port-o-potties) positioned securely, away from drainage features, and maintained to prevent leaks or spills? (CGP 2.3.3.f; CPP 2.4.4)
17. Are designated areas for concrete, paint, and other construction material washout properly managed to prevent contamination of stormwater? (CGP 2.3.4; CPP 2.1.1)

18. Do the storm water controls (e.g., erosion, sediment, and pollution prevention measures) match those indicated on the site map, and are they designed, installed, and maintained according to BMP specifications in the SWPPP, considering precipitation, slope, soil type, and construction phase adjustments? (CGP 2.1.1-2.1.4; CPP 4.1.1)

Comments (Summarize key observations from the inspection, including any deficiencies, corrective actions needed, and any discussions with the site operator):

Part 2: SWPPP Pre-Site Review (CGP Part 7; CPP Part 4)
(Ensure all information is accurate and up to date)
List:
Yes, No, N/A
1. Has a pre-construction review of the SWPPP been conducted by the appropriate municipal agency?
2. Are contact names, positions, responsibilities, and telephone numbers of the Storm Water Team and all other responsible parties listed in
the SWPPP? (CGP 7.3.1; CPP 4.2.1)
