			 will comply with OAR
			 340-096-0070:
			 Performance Measures or with section (6) of this rule, the department may
			 require the composting facility to revise the Operations Plan.
(4) After receiving a proposed Operations
			 Plan, the department will provide the facility operator with an opportunity to
			 meet with the department and discuss the composting facility, the proposed
			 Operations Plan, and any department concerns or issues related to the facility
			 and the plan. Upon final department approval of an Operations Plan, the

(5) All
			 Operations Plans subject to this rule must address the elements set out in this
			 section.

			 proposed uses of the compost, biogas, digestate and other products and
			 materials.
(b) Protection of
			 Surface Water. The Operations Plan must describe how the facility will be
			 designed and operated to comply with OAR
			 340-096-0070(1)
			 and (2)  by describing the operational
			 procedures and any structures the facility will use to manage any leachate and
			 any stormwater generated at the facility. Any facility that manages leachate or

			 340-096-0120:
			 Groundwater.
(d) Odor control. The
			 Operations Plan must describe the methods and procedures the facility will use
			 to comply with OAR
			 340-096-0070(4)

			 the Operations Plan must describe methods the facility will use to comply with
			 OAR
			 340-096-0140:
			 Pathogen Reduction, including:
(A) Methods
			 the facility will use to comply with OAR
			 340-096-0070(5)
 
			 to achieve the pathogen reduction standards set out in OAR
			 340-096-0140(2);
(B) Methods the facility will use
			 for sampling and testing of composted material and digestate to assure that the
			 required human pathogen reduction is being achieved; and
(C) Procedures the facility will use for
			 handling composted material and digestate that does not meet pathogen reduction
			 standards.
(f) Vector
			 attraction. The Operations Plan must describe methods the composting operation
			 will use to comply with OAR
			 340-096-0070(6)
 
			 to minimize the attraction of vectors such as rats, birds, flies.
(g) Closure. The Operations Plan must include
			 a Closure Plan that must address:

			 products and materials;
(C)
			 Disposal of processed compost, biogas, digestate, and other products and
			 materials that, due to concentrations of contaminants, cannot be marketed or
