These answers are not intended to create significant new guidance or require any changes to previously accepted labeling. The Agency will contact registrants directly about how to correct problematic labels as appropriate. Changes to EPA accepted labeling will only be required in accordance with standard agency procedures. These answers are primarily based on federal law, regulations and policies implemented by EPA. States, tribes, territories, and other federal agencies may have additional requirements relevant to their jurisdictions.

How is "greenhouse," as a use site, defined by EPA? Would EPA consider cold frames to be greenhouses? (LC10-0393; 3/3/11)
For the purposes of the Worker Protection Standard (WPS), 40 CFR 170.3 defines "greenhouse" as "any operation engaged in the production of agricultural plants inside any structure or space that is enclosed with nonporous covering and that is of sufficient size to permit worker entry. This term included, but is not limited to, polyhouses, mushroom houses, rhubarb houses, and similar structures." EPA has not defined "greenhouse" in the context of use sites but the WPS definition is instructive. If a cold frame is enclosed with nonporous covering and is large enough to permit worker entry, it would likely be considered a greenhouse.
Cleanout and disinfection of crawl spaces (area underneath houses) is a new service being provided by a number of PCO companies. We are having difficulty determining whether disinfectants can legally be used in crawl spaces. Often the sites on disinfectant labels are very broad and seem to allow treatment in any area of a structure (including the crawl space), but then the specific directions only cover areas with non-porous surfaces inside of a structure. It would be helpful for EPA to address this new use pattern and in the meantime we would appreciate some guidance on when disinfectants with current labels can be used in crawl spaces. (LC08-0176; 10/18/08)
The Agency does not have a standard definition for crawl spaces. As a result, the user must refer to the label of the disinfectant product to determine whether the product can be used to treat crawl spaces. Typical components of a crawl space include ground and bare wood. The Agency considers these surfaces to be porous surfaces. These types of surfaces cannot be treated unless the label contains directions that would allow the product to be used to disinfectant porous surfaces. If the label has language limiting applications to hard non-porous surfaces, application to a crawl space with porous surfaces would not be permitted.
