To qualify, such facility, device, fixture, equipment, structure, specialty chemical, or bioaugmentation product must be used, installed, or constructed to meet a law implemented by, or a condition of a permit issued by, the Department of Environmental Protection; however, such exemption shall not be allowed unless the purchaser signs a certificate stating that the facility, device, fixture, equipment, structure, specialty chemical, or bioaugmentation product to be exempted is required to meet such law or condition.

This exemption does not include solid waste collection vehicles, compactors, graders, or other earthmoving equipment.
(3) For the purposes of this section, “specialty chemicals” means those chemicals used to enhance or further treat wastewater, including, but not limited to, defoamers, nutrients, and polymers, and “bioaugmentation products” means the microorganisms used in waste treatment plants to break down solids and consume organic matter.
