Method for determining percent
foreign matter.
Foreign matter content shall be
determined by passing a dried, weighed sample of not less than one hundred
grams of compost through a U.S. standard No. 5 sieve (four millimeter). The
material remaining on the screen shall be inspected and the foreign matter
shall be separated and weighed. The weight of the foreign matter divided by the
total weight of the compost sample and multiplied by one hundred shall be the
per cent dry weight of the foreign matter content.

[Comment: The parameters identified
for testing in table 4 have no associated concentration limits. The analysis is
necessary to ensure that compost quality is appropriate for the recipient's
specific use of the compost product.
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.]
(2) Upon written notification by the
director, the owner or operator shall sample and test for additional parameters
as deemed necessary to ensure the standards are appropriately protective of
public health and safety and the environment.
