Steve Brown's May 7 article -- "Engineer gets down and dirty on manure composting" -- gave sound advice for farmers and ranchers who want to manage manure through composting.
And assisted by Conservation Districts around Washington, folks should have no trouble finding help when they want to compost manure on their farms.
However, there's more to the story than was reported in the article. For example, it stated, "As far as permitting goes, (Rich) Geiger said, 'Keep it simple and you won't need a permit.'"
While that is true for many operations, there are criteria to be met and some circumstances will require a permit. The criteria and permit oversight are intended to protect public health and resources such as air and water quality.
In Washington, our compost regulations, WAC 173-350-220, mostly apply to commercial composters. They handle large volumes of yard debris, food scraps and other organic materials from residential, commercial and agricultural sources. Within those regulations, several exemptions to the solid waste handling standards apply to farms, small composters and vermicomposters -- worm wranglers. Qualifying for those exemptions means a facility must meet specific volume, feedstock and finished product standards.
While "simple" is often the best way to compost, it may not accurately determine whether a facility needs a permit or a conditional exemption from the permit.
Four different exempt categories apply to agricultural composting. Two of these are limited by compliance with Farm Management or Dairy Nutrient Management Plans. As mentioned above, depending on how the material is managed, different requirements apply. These may include:
* Annual reporting and notification to the local health department.
* Air, water quality and vector attraction controls (typically rats and flies).
* Finished compost testing for pathogens, metals, inert materials and stability.

When it's done right, composting creates solutions where there may have been problems. Done right, compost helps create healthy soils that hold water, resist erosion and slowly release nutrients back to the plants and animals.
