RRP vs abatement In Missouri, anyone who does lead abatement (removal, replacement, enclosure or encapsulation of lead-based paint) must be licensed by the Department of Health and Senior Services, and the company must hold a lead abatement contractor license. Ordinary renovation work in pre-1978 housing falls under EPA's separate RRP certification instead.

Anyone who does lead abatement work in Missouri needs a license from the Department of Health and Senior Services (DHSS). That covers abatement supervisors, workers, inspectors, risk assessors and project designers. The company that employs them needs a separate lead abatement contractor license. Training must come from a DHSS-accredited provider. DHSS describes its job this way: “We are responsible for licensing lead abatement professionals, which includes lead abatement supervisors, lead abatement workers, lead inspectors, risk assessors and project designers.” It also licenses “lead abatement contractors, which are the companies or firms that employ the lead professionals,” and runs random inspections of those contractors. ## What counts as lead abatement? Abatement means removal, replacement, enclosure or encapsulation of lead-based paint. DHSS says anyone “performing any abatement strategies (removal, replacement, enclosure and encapsulation) must still be licensed” by the department and must notify it as required. Our [lead abatement](https://aes.multisites.ai/lead-abatement) page covers these methods, and the glossary explains [lead abatement](https://aes.multisites.ai/glossary/lead-abatement) in plain terms. Abatement is a state license. Work that falls short of abatement can fall under a federal rule instead. That rule is the next topic. ## What is the RRP rule, and how is it different? RRP stands for Renovation, Repair and Painting. It is an EPA rule that governs renovation work in housing built before 1978 and in child occupied facilities. DHSS summarizes it: any contractor whose work affects more than 6 square feet of interior painted surface, or 20 square feet of exterior, “must be a certified renovation firm” with certified renovators on staff. RRP certification Missouri lead abatement license Who issues it U.S. EPA Missouri DHSS What it covers Renovation, repair and painting that disturbs painted surfaces in pre-1978 housing Removing, replacing, enclosing or encapsulating lead-based paint Size trigger More than 6 sq ft inside or 20 sq ft outside The work is abatement Who holds it Firm and certified renovators Individual professionals and the contractor company The two systems do not replace each other. DHSS says the RRP regulations “have not altered federal or state regulations on lead abatement.” Read the [RRP rule](https://aes.multisites.ai/glossary/rrp-rule) entry for definitions. ## Why does the age of the house matter? Houses built before 1978 may contain lead paint, and older ones are more likely to. DHSS says “any housing built prior to 1978 may be considered suspect.” In Missouri, it estimates 60% of dwellings built from 1960 to 1978 contain [lead-based paint](https://aes.multisites.ai/glossary/lead-based-paint). That rises to 80% for 1940 to 1959 and as high as 90% for dwellings built before 1949. So a remodel of a house built in the 1920s likely involves lead paint and needs lead-safe planning. Our guide to [lead paint in pre-1978 homes](https://aes.multisites.ai/guides/lead-paint-in-pre-1978-homes) goes deeper, and our [lead paint facts](https://aes.multisites.ai/lead-paint-facts) page covers health basics. ## Who can test paint for lead? A licensed lead-based paint inspector or risk assessor, if the method is paint chip sampling. DHSS notes that EPA allowed certified renovators to collect paint chips for lab analysis, but “in Missouri, paint chip sampling must be performed by a licensed lead-based paint inspector or risk assessor.” Renovators can still use the other test methods in the RRP rule. An [XRF analyzer](https://aes.multisites.ai/glossary/xrf-analyzer) is one common inspector tool. ## How do you check that a contractor is licensed? Ask for the license and look it up. DHSS keeps a page called “Missouri Licensed Lead Professionals” on its lead licensing site, and a page of disciplinary actions. Check three things: 1. Is the contractor company licensed as a lead abatement contractor, for abatement work? 2. Are the on-site supervisor and workers individually licensed? 3. For renovation-only work, is the firm EPA RRP certified? If a bid cannot answer these, move on. Questions about a license go to the DHSS Lead Licensing Program at 573-526-5873 or [lead@health.mo.gov](mailto:lead@health.mo.gov). ## What if I hire a general contractor for a remodel? Ask the general contractor which firm handles the lead work. A remodel of a pre-1978 home touches the RRP rule if it disturbs more than 6 square feet of interior or 20 square feet of exterior painted surface. DHSS says that work needs a certified renovation firm and certified renovators. If the plan includes removing, replacing, enclosing or encapsulating lead-based paint on purpose, that is abatement, and abatement needs licensed professionals. Put the answer in the contract. Name who holds which credential, and ask for the license or certification numbers. Then check them on the state and EPA sites. A general contractor who says “we handle it” without naming a licensed or certified firm has not answered your question. DHSS also runs random inspections of lead abatement contractors, so compliance is something the state checks. ## Next step Advanced Environmental Services lists [lead abatement](https://aes.multisites.ai/lead-abatement) among its services.

Missouri's lead program says abatement work must be done by licensed professionals. The state page does not give a homeowner exemption in the text we read. Call the DHSS Lead Licensing Program at 573-526-5873 before you start. Do not scrape, sand or burn lead paint on your own. ### What is the difference between RRP certification and a lead abatement license? RRP is an EPA certification for renovation firms and renovators who disturb painted surfaces in pre-1978 housing. A lead abatement license is a Missouri DHSS license for work that removes, replaces, encloses or encapsulates lead-based paint. The RRP rule did not change Missouri's abatement licensing. ### Who can take paint chip samples in Missouri? A licensed lead-based paint inspector or risk assessor. DHSS says EPA-certified renovators who are not licensed in one of those roles cannot use paint chip sampling in Missouri. Other test methods in the RRP rule are still open to them. ## Terms on this page - [Lead-based paint](https://aes.multisites.ai/glossary/lead-based-paint) - [Lead abatement](https://aes.multisites.ai/glossary/lead-abatement) - [Encapsulation](https://aes.multisites.ai/glossary/encapsulation) - [XRF analyzer](https://aes.multisites.ai/glossary/xrf-analyzer) - [RRP rule](https://aes.multisites.ai/glossary/rrp-rule) ## Sources 1.
