CANTON â St. Lawrence County Planning Office Director Jason C. Pfotenhauer gave an update Monday to the county Board of Legislators on the Lead-Based Paint Hazard Reduction Program. The program, which has been going on for more than a year, began because St. Lawrence County was identified as one of the counties where incidence of elevated lead levels increased from 2003 to 2012. Changes were also anticipated in New York state standards for elevated blood lead levels, reducing the acceptable amount from 10 micrograms per deciliter of blood to 5 mg/dL. Lead hazard assessments have been completed on 16 units, while seven units have achieved lead clearance after lead hazard control work.
