The US Composting Council has signed on in support of a letter written by the North East Biosolids and Residuals Association (NEBRA) and North West Biosolids opposing draft amendments to Alaska’s Oil and and Hazardous Substances Pollution Control regulations (click here to read more). The amendments concern cleanup of Polyfluoroalkyl Substances.
The letter outlines the concern by the signing organizations for the potential for unintended consequences. The letter states, “ADEC’s proposed migration to groundwater soil cleanup standard for five of the six PFAS are inappropriate and indefensible based on current scientific knowledge,”, and recommends that ADEC eliminate the migration to groundwater pathway soil cleanup values for the five PFAS chemicals other than PFBS.
“The high levels of uncertainty and the ubiquitous dispersion of several PFAS chemicals in the environment in many matrices and their unusual chemical characteristics makes their regulation particularly challenging,” the letter states. The organizations recommend that organic residuals and soil amendments added to soils, including composts, manures, and biosolids should be exempt.
