MOLYBDENUM

Goal: Allow in-state, year-round distribution of all MWRA pellets.


New Challenges for MWRA Pellets

Our victory on establishing a science-based, defensible molybdenum limit, which would allow for the year-round, in-state, beneficial reuse of MWRA pellets, was thrown a curve ball by the recently released Department of Agricultural Resources Plant Nutrient Application Requirements for Agricultural Land Regulations 330 CMR 3.00.

In essence, the scope of the regulation has been dramatically increased, making it practically nonviable for land-use application of MWRA pellets in state.

In our comments, the Advisory Board states that “we laud DAR’s goal to regulate and enforce the registration and application of plant nutrients put on our soil to reduce phosphorus loadings to water bodies. However, all biosolids are not the same and need to be reviewed differently.” Click through to access MWRA and MWRA AB comments.

We will work closely with MWRA staff and DAR to ensure the in-state beneficial reuse of MWRA pellets are not only a goal, but also an attainable reality.

Comments and Recommendations History

FY 2015 (printed May 2014)

  • AB recommended that the Authority begin immediately to address molybdenum limits … with the goal of ensuring … pellets can be placed in-state throughout the entire year … and present a specific and detailed plan to do so to the MWRA Board by October 2014 (page 89; #29).
