A. Except as provided in subsection B, the only nonpoint nutrient credits that shall be transferred pursuant to either (i) § 62.1-44.15:35 or (ii) subsections B, C, and D of § 62.1-44.19:21 are nutrient credits generated by the private sector, including credits generated by the private sector pursuant to an agreement with a public body.
B. Other than for purposes of subsection A of § 62.1-44.19:21, nutrient credits or sediment credits generated by a project undertaken by a public body, including a locality, and certified by the Department shall be used only by such public body and only for the purpose of compliance with the provisions of this chapter by such public body’s project. For the purposes of this subsection, the term “public body’s project” means a project for which the public body is the named permittee and for which no third party conducts any lease, sale, grant, transfer, or use of the project or its nutrient or sediment credits.

Except for a water reclamation and reuse project at a treatment works, no more than 10 pounds per year of phosphorous allocation may be applied toward a single project’s postconstruction phosphorus control requirement.
