1. A nutrient management plan approved by the Department of Conservation and Recreation shall be required for application sites prior to board authorization under specific conditions, including but not limited to:

a. Sites operated by an owner or lessee of a confined animal feeding operation as defined in subsection A of § 62.1-44.17:1 of the Code of Virginia, or confined poultry feeding operation as defined in subsection A of § 62.1-44.17:1.1 of the Code of Virginia;

b. Sites where land application more frequently than once every three years at greater than 50% of the annual agronomic rate is proposed;

c. Mined or disturbed land sites where land application is proposed at greater than agronomic rates; and

d. Other sites based on site-specific conditions that increase the risk that land application may adversely impact state waters.

2. Where conditions at the land application site change so that it meets one or more of the specific conditions identified in subdivisions 1 a through d of this subsection, an approved nutrient management plan shall be submitted prior to any future land application at the site.

3. The nutrient management plan shall be available for review by the department at the land application site during biosolids land application.

4. Within 30 days after land application at the site has commenced, the permit holder shall provide a copy of the nutrient management plan to the farm operator of the site, the Department of Conservation and Recreation and the chief executive officer or designee for the local government unless they request in writing not to receive the nutrient management plan.

5. The nutrient management plan must be approved by the Department of Conservation and Recreation prior to land application for application sites where the soil test phosphorus levels exceed the values in Table 1 of this section. For purposes of approval, permittees should submit the nutrient management plan to the Department of Conservation and Recreation at least 30 days prior to the anticipated date of land application to ensure adequate time for the approval process.
