Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) A green material composting operation may
				  have no more than 12,500 cubic yards of feedstock, chipped and ground material,
				  amendments, additives, active compost, and stabilized compost on-site at any
				  one time. Green material composting operations shall comply with the EA
				  Notification requirements set forth in Title 14, California Code of
				  Regulations, Division 7, Chapter 5.0, Article 3.0 (commencing with section
				  18100) and with the applicable
				  requirements specified in this Chapter.
(1)
				  These operations shall be inspected by the EA at least once every three (3)
				  months unless the EA approves, with Department concurrence, a reduced
				  inspection frequency. 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 but in no case shall the frequency be less than once per calendar
				  year.
[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) To allow
				  for seasonal variations in the rate at which stabilized compost is utilized by
				  agricultural users and other consumers, the operator may request in writing
				  that the stabilized compost be temporarily excluded from the calculation of the
				  12,500 cubic yard maximum material allowed on-site ("seasonal storage
				  adjustment"). At the EA's discretion, the seasonal storage adjustment for
				  stabilized compost may be extended to the storage time and storage volume
				  specified in the land use entitlement for the site if the EA finds, on the
				  basis of substantial evidence, that the adjustment does not increase the
				  potential harm to public health and safety, and the environment. The EA shall
				  respond in writing to the operator's request within 30 days of receipt. The EA
				  may impose any reasonable conditions on the seasonal storage adjustment. The
				  initial term seasonal storage adjustment may not exceed the storage time
				  specified in the land use entitlement or 30 days, whichever is less. The
				  seasonal storage adjustment may be extended by one or more additional 30-day
				  periods not exceeding the storage time specified in the land use entitlement or
				  a total of 90 days per calendar year, whichever is less.
(A) With its request for a seasonal storage
				  adjustment, the operator shall submit to the LEA a storage plan containing the
				  following:
1. A description of the storage
				  capacity including the assumptions, methods, and calculations used to determine
				  total storage capacity.
2. The
				  maximum and average lengths of time the compostable material will be
				  stored.
3. A schematic drawing
				  showing the general layout of the operation and the location(s) where all
				  materials at the site are stored with specific identification of the proposed
				  location of the excess material.
4.
				  A description of any additional fire prevention, protection and control
				  measures needed to minimize the risk of fire from the temporary increase in
				  site capacity and to control and extinguish any such fires, which measures
				  shall be approved by the local fire authority.
5. Where applicable, any revisions to the
				  odor impact minimization plan necessary to address the storage of the
				  additional material or a statement, with supporting information, that no
				  revisions are necessary.
