§502.500. Purpose, Scope, and Applicability

The requirements in this Subpart are intended to minimize the transportation of nitrogen and phosphorus into the waters of the United States to comply with the nutrient management plan.

 

a)         The requirements in this Subpart apply to CAFOs required to obtain an NPDES permit. Unpermitted large CAFOs claiming an agricultural stormwater exemption under Section 502.102 are not required to have a nutrient management plan but must comply with the requirements listed in Section 502.510(b) to qualify for the exemption.

 

b)         The CAFO owner or operator must develop, submit, and implement a site-specific nutrient management plan.  This plan must specifically identify and describe practices that will be implemented to assure compliance with this Subpart and the livestock waste discharge limitations and technical standards of Subparts F, G, and H.
