Lead Paint: The EPA’s New Rule

Lead Paint The EPA's New Rule

The Environmental Protection Agency’s (EPA) Lead: Renovation, Repair, and Painting Rule, issued in 2008, was to take formal (enforceable) effect on April 22, 2010. However, due to difficulties with compliance, the EPA has extended this deadline to December 30, 2010.

This rule mandates a number of specific practices for contractors to mitigate the health hazards associated with disturbance of lead-based painted surfaces in homes, child care facilities, and schools constructed prior to 1978.1 Under this rule, all contractors in the U.S. conducting work on lead-based painted surfaces are required to be EPA certified and to follow specified work practices for preparation, clean-up, and record keeping. Painters, plumbers, electrical workers, general contractors, and a miscellany of other service providers will be affected. The rule applies to the disturbance of lead-based painted interior surfaces of six or more square feet and exterior surfaces of 20 square feet or more. Guidelines are also provided for window replacement and demolition in such facilities and homes. Under the statute, contractors not in compliance could be fined as much as $37,500 a day.2

Reducing Errors through Multi-Increment Sampling

Wednesday, August 18th, 2010

By Gregory Salata, Ph.D.

Multi-Increment Sampling

The objective of environmental sampling is to quantify contamination at a given location. In situations where sample collection may result in discrete samples of a heterogeneous nature, results may be biased based on the particle size of each sub-aliquot collected at the site. One option to help reduce the errors associated with non-uniform sample composition is to use multi-increment sampling (MIS) to create a representative, homogeneous aliquot for analysis of analytes.

Proposed NPDES Rule Requires ‘Sufficiently Sensitive’ Test Methods

Monday, August 2nd, 2010

Sufficiently Sensitive Test Methods

In a Federal Register notice published June 23, the EPA proposed changes to its permitting program under the Clean Water Act (CWA) to ensure the use of sufficiently sensitive analytical methods for monitoring chemical pollutants in discharge water.

Specifically, the new rule affects the CWA’s National Pollutant Discharge Elimination System (NPDES). Its purpose is to specify that applicants and permittees must use analytical methods that are capable of detecting and measuring pollutants at, or below, current water quality criteria.
