Article 1 - In-Vessel Digestion Operations and Facilities Regulatory Requirements
Section 17896.9 - Dairy in-Vessel Digestion Operations

(1) These operations shall be inspected by the EA at least once a month for the first 12 months of operation. After the first 12 months of operation the EA may approve, with Department concurrence, a reduced inspection frequency of once every three months. After the first 24 months of operation the EA may approve, with Department concurrence, a reduced inspection frequency of once per calendar year. The EA may approve a reduced inspection frequency only if it will not pose an additional risk to public health and safety or the environment.

[NOTE: See section 18083(a)(3) for additional enforcement agency and Department requirements regarding the approval or denial of requests for reducing the frequency of inspections.]

(2) Any imported materials delivered to the dairy must be pumped or off-loaded directly into a covered, leak-proof container and then pumped, or diluted or slurried and then pumped, and co-digested in an in-vessel digester at a dairy. The pumped material may be screened, otherwise separated or treated prior to in-vessel digestion, but must be processed and conveyed in a contained system. Any separated material at the dairy that is not suitable for in-vessel digestion and has no beneficial use shall be further managed as a solid waste.
