Page 1 of 3 di Robert McClellon [EH] From: Robert McClellon [EH] Sent: Tuesday, August 17, 2010 11:10 AM To: Donna Heran [EH] Subject: RE: Olivera Egg Ranch Donna, I have had some recent involvement at the Olivera Foods Site. Mr. Olivera is currently looking to improve manure management onsite. The changes at the site include the addition of a fly ash drying pad in side to the secondary pond. Mr. Olivera has submitted amendment to the Manure Management plan to conduct windrow manure drying operation. This operation is similar to a composting operation in appearance, but is for the purposes of drying. I made an un-announced site visit on August 9, 2010 to check on the windrow drying of the manure. During the site visit I checked the windrows for temperature. The temperatures were below 122 degrees F (Title 14 California Code of Regulations trigger for regulation). While onsite I went to the West end of Briggs Road to assess the odors from the Olivera Foods lagoons. The earliest detection of odor from the operation was at 500 feet from the lagoon. The odor were initially light but increased as I approached the lagoon. The checked the lagoon for a floating solids mat. The mat covered 40-50% of the lagoon. My concern with the mat is that it could increase the incidence of fly breeding. I noticed that the site manager(Mr. John Den dulk) arrived at the site. I went over and spoke with him. I explained that it was just a spot check and that I was not investigating a complaint. I asked Mr. Den dulk to agitate the lagoon and break up the solids mat. He stated that he had concerns that by breaking up the mat he would cause more odor, but agreed to do it. During the conversation Mr. Den Bulk mentioned that Mr. Olivera is currently is seeking a permit to install a bio digester at the site to handle the manure and to use the methane from that process to generate electricity. Mr. Olivera has made efforts to lower impacts from his operation on the surrounding community. Some of the changes are still in process (not finished). The EHD received an odor complaint on August 10, 2010. 1 made a site visit on August 11, 2010. During the site visit I spoke with Mr. Den Bulk and he confirmed that they agitated the lagoon on August 10, 2010, for approximately 1 hour. I called the complainant back and directed them to call APCD and they indicated that they have done so already. The EHD oversees Olivera Foods operation for the manure management practices, solid waste management, vector control and sanitation. The EHD has made it a practice to respond to all complaints. The complaints received by the EHD for odor can be an indication that the operation has other issues, so we respond. If issues exist that are under the EHD's authority then we will follow up. If there are not then we refer the issue to APCD.
