(A) The compost quality standards in this
			 paragraph are applicable to all compost produced from yard waste, animal waste,
			 agricultural plant materials, food scraps, dead animals, raw rendering material, and alternative
			 materials. The owner or operator shall have the samples collected
			 in
			 accordance with rule
			 3745-560-225
			 of the Administrative Code analyzed using the methods
			 specified in tables 1 to 4 of this rule or other
			 methods authorized by the director pursuant to rule 3745-560-06 of the
			 Administrative Code. Test results shall demonstrate that concentration
			 limits are not exceeded for the parameters listed in  tables
								1 to 3 of this rule. The
			 owner or operator shall also have the samples analyzed for the parameters
			 identified in table 4, which have no associated concentration limits, to ensure
			 usage of compost product in accordance with accepted agricultural,
			 silvicultural, or horticultural practices.

[Comment:
Acceptable levels of maturity will vary according to end-user
				application (note: check date of maturity test).
Acceptable pH level will vary according to end-user application
				and will generally be in the 5.5 - 8.5 range.
Acceptable levels of soluble salts will vary according to
				end-user applications. The optimal ranges for growing media (compost amended
				soil) is 0.5 to 4.5 millimho per centimeter.
Compost producers may provide pH and soluble salts information
				in product literature for the intended end-user application that reflect user
				industry standards.]

			 ,
			 safety, or the environment.
(1) Upon written notification
			 from
			 Ohio EPA, the owner or operator shall provide information regarding the
			 feedstocks, bulking agents, additives, compost, or compost product including
			 but not limited to the following:
