NY Water/Wastewater Operator cheat sheet

Environmental Protection, Permits, and Operator Safety

• NY SPDES permits control discharges to surface waters; effluent limits, monitoring frequency, and reporting deadlines are enforceable conditions, not recommendations.

• Discharge Monitoring Reports (DMRs) are submitted monthly or as specified; late or inaccurate DMRs are permit violations subject to penalties.

• Confined space entry: atmospheric testing order is oxygen first, then combustibles, then toxics; acceptable oxygen is 19.5–23.5%, and entry requires a permit and attendant.

• Hazardous gas thresholds: hydrogen sulfide IDLH is 100 ppm, carbon monoxide 1,200 ppm, methane LEL is 5% in air; continuous monitoring is required.

• Chlorine gas is heavier than air; leaks pool at low points. Use ammonia solution to detect leaks (white cloud) and never enter without SCBA and backup.

• Lockout/tagout: isolate energy sources, verify zero energy, apply locks and tags, and only the person who applied a lock may remove it.

• Chemical feed calculations: dose (mg/L) × flow (MGD) × 8.34 = pounds per day; use this for chlorine, alum, polymer, and fluoride feed settings.

• Personal protective equipment and hazard communication: SDS sheets must be accessible, and employees trained on chemical hazards under OSHA Hazard Communication standard.

• Water and wastewater operator certification in NY is graded (Class 1A–4A for water, 1–4 for wastewater) and requires continuing education for renewal.
