						<section id="B1" class="indent-1"><p><span class="prefix-number">1.</span> Establish procedures for the certification and registration of credits, including:
				a. Certifying credits that may be generated from effective nutrient controls or removal practices, including activities associated with the types of facilities or practices historically regulated by the <span class="dictionary">Board</span>, such as water withdrawal and treatment and wastewater collection, treatment, and beneficial <span class="dictionary">reuse</span>;
				b. Certifying credits that may be generated from agricultural and urban stormwater best management practices, use or management of manures, managed turf, land use conversion, stream or <span class="dictionary">wetlands</span> projects, shellfish aquaculture, algal harvesting, and other established or innovative methods of nutrient control or removal, as appropriate;
				c. Establishing a process and <span class="dictionary">standards</span> for wetland or stream credits to be converted to <span class="dictionary">nutrient credits</span>. Such process and <span class="dictionary">standards</span> shall only apply to wetland or stream credits that were established after July 1, 2005, and have not been transferred or used. Under no circumstances shall such credits be used for both wetland or stream credit and <span class="dictionary">nutrient credit</span> purposes;
				d. Certifying credits from multiple practices that are bundled as a package by the applicant;
				e. Prohibiting the certification of credits generated from activities funded by federal or state water quality grant funds other than controls and practices under subdivision B 1 a; however, baseline levels may be achieved through the use of such grants;
				f. Establishing a timely and efficient certification process including application requirements, a reasonable application fee schedule not to exceed $10,000 per application, and review and approval procedures;
				g. Requiring public notification of a proposed <span class="dictionary"><span class="dictionary">nutrient credit</span>-generating entity</span>; and
				h. Establishing a timeline for the consideration of certification applications for land conversion projects. The timeline shall provide that within 30 days of receipt of an application the <span class="dictionary">Department</span> shall, if warranted, conduct a site visit and that within 45 days of receipt of an application the <span class="dictionary">Department</span> shall either determine that the application is complete or request additional specific information from the applicant. A determination that an application for a land conversion project is complete shall not require the <span class="dictionary">Department</span> to <span class="dictionary">issue</span> the certification. The <span class="dictionary">Department</span> shall deny, approve, or approve with conditions an application within 15 days of the <span class="dictionary">Department</span>&#x2019;s determination that the application is complete. When the request for credit release is made concurrently with the application for a land conversion project certification, the concurrent release shall be processed on the same timeline. When the request for credit release is from a previously approved land conversion project, the <span class="dictionary">Department</span> shall schedule a site visit, if warranted, within 30 days of the request and shall deny, approve, or approve with conditions the release within 15 days of the site visit or determination that a site visit is not warranted. The timelines set out in this subdivision shall be implemented prior to adoption of <span class="dictionary">regulations</span>. The <span class="dictionary">Department</span> shall release credits from a land conversion project after it is satisfied that the applicant has met the criteria for release in an approved nutrient reduction implementation plan. <a id="paragraph-227739" class="section-permalink" href="https://vacode.org/62.1-44.19_20/#B1"><i class="fa fa-link"/></a></p></section>

				b. Baselines established for agricultural practices, which shall be those actions necessary to achieve a level of reduction assigned in the Virginia Chesapeake Bay TMDL Watershed Implementation Plan or approved TMDLs as implemented on the tract, field, or other land area under consideration;
				c. Baselines for urban practices from new development and redevelopment, which shall be in compliance with postconstruction nutrient loading requirements of the Virginia Stormwater Management Program <span class="dictionary">regulations</span>. Baselines for all other existing development shall be at a level necessary to achieve the reductions assigned in the urban sector in the Virginia Chesapeake Bay TMDL Watershed Implementation Plan or approved TMDLs;
				d. Baselines for land use conversion, which shall be based on the pre-conversion land use and the level of reductions assigned in the Virginia Chesapeake Bay TMDL Watershed Implementation Plan or approved TMDLs applicable to that land use;
				e. Baselines for other nonpoint source credit-generating practices, which shall be based on the Virginia Chesapeake Bay TMDL Watershed Implementation Plan or approved TMDLs using the best available scientific and technical information;
				f. Unless otherwise established by the <span class="dictionary">Board</span>, for certification within the Chesapeake Bay Watershed a credit-generating practice that involves land use conversion, which shall represent controls beyond those in place as of July 1, 2005.
