BAAQMD & LEA response to recent odors

Below is the written response from BAAQMD & LEA regarding the recent increase of odor:

BAAQMD : “We have also been investigating what source(s) may be contributing to the odor spike the last few evenings. Our Inspector was in Milpitas in the evenings this week and observed some trailers at the MRF that were overfilled and contributing to localized odors at the facility. Jay took pictures of the untarped trailers and I can ask him to forward the pictures he took. Regarding the CASP, I will need to check in with our staff to see if there were compliance concerns and get back to you. They also conducted patrols at ZWED and the wastewaster treatment facility but didn’t observe odors from those facilities. “

LEA : “The mild odor we could detect we thought was most likely compost and it was in the afternoon (approximately 2:30 – 3:30 PM). We made this determination based on what direction the prevailing winds were coming from (NW) and where we could detect the odor (SE Milpitas) which is downwind from the compost operations. “
