Environmental rules: EPA lead-safe certification for any pre-1978 home, asbestos and transite pipe, and stormwater
Three environmental rules reach into ordinary plumbing work and are enforced by agencies most plumbers never meet until the fine arrives. The federal lead rule makes any work for pay in a pre-1978 home that disturbs painted surfaces, which a repipe, a wall opening, or a tub replacement does, a job for an EPA-certified firm using a certified renovator and lead-safe practices, with a pamphlet to the customer before starting. Asbestos is in the transite pipe, the old duct wrap, and the floor tile a plumber cuts through; California's license law exempts transite pipe work from the CSLB asbestos certification but Cal/OSHA's asbestos standard still applies to every employee who touches it. And the water from a jetter, a heater flush, or a saw cut may not go down the storm drain. This lesson gives each rule with its trigger, what compliance costs, and what enforcement costs.
What the full lesson covers
- EPA RRP: any renovation for compensation in housing built before 1978 that disturbs more than 6 square feet of painted surface per interior room (20 exterior) must be done by an EPA-certified firm with a certified renovator, lead-safe work practices, the "Renovate Right" pamphlet delivered and acknowledged before work, and three years of records. Firm certification is a fee and a five-year renewal; the renovator course is one day. A repipe that opens walls in a 1965 house is covered.
- Asbestos: transite (asbestos cement) water and sewer pipe, pre-1980s duct insulation, floor tile and mastic, and drywall joint compound may contain it. B&P 7058.5 exempts transite pipe installation, maintenance, and repair from the CSLB asbestos certification, but 8 CCR 1529 applies to every employee exposed, with a competent person, wet methods, respiratory protection where required, and training; abatement of 100 square feet or more of other materials needs the C-22 or CSLB certification and DOSH registration.
- Never dry-cut transite; never break it; wrap and dispose per the landfill's rules; and when the job is removal of more than the pipe, hand it to a certified abatement contractor.
- Stormwater: jetting water, drain cleaning waste, water heater flush water with sediment, saw-cut slurry, and concrete washout do not go into the gutter or the storm drain; capture and discharge to the sanitary sewer where the sewer agency allows, or contain and dispose. Cities enforce with fines per discharge.
- The hazard communication rule covers the solvents, cements, and drain chemicals on the truck: safety data sheets available, containers labeled, employees trained.
