Rules Implementation Resources
Falls Lake Status Report
The Falls rules require the Division of Water Resources to report to the Environmental Management Commission on specific aspects of progress in the Falls Lake watershed in January 2016 and every five years thereafter. This report satisfies that requirement by providing an update on implementation of the rules, evaluating changes in nutrient loading to the lake, detailing progress towards achieving the chlorophyll a water quality standard, and characterizing advances in scientific understanding and control and accounting technologies while identifying future research and data needs.
The Falls New Development rule required the division to develop a New Development Model Program to assist local governments in developing their local programs. The N.C. Environmental Management Commission approved the Division of Water Resource's Model Program on March 10, 2011. The Model Program contains a Model Ordinance and a Nutrient Loading Accounting Tool. Local governments had until Aug. 10, 2011 to develop and submit local programs.

Falls Lake Stormwater Accounting Tool
The Falls Rules also required the division to develop a Nutrient Loading Accounting Tool to estimate nutrient loading from new development and loading changes due to BMP implementation. The division contracted with N.C. State University's Stormwater Team to develop this tool. Two versions are available below.
*Note (May 10, 2013): The tools found below are Version 2.0. Several errors were identified in the original tool such that under certain limited development scenarios, it produced erroneous results. Those errors were corrected and none of the tool's other functions have been changed. To help track versions, all sheets in the tool include a label at the top noting"Ver2.0". Please begin using Version 2.0 from this point forward.
May 13, 2014 Memo to Developers and Local Governments: This memo discusses how local givernments may voluntarily choose to allow volume matching, as shown by the Storm-EZ tool, to meet the new development stormwater nutrient requirements.
July 18, 2012 Memo to Developers & Local Governments This memorandum identifies an issue in the design of the approved Jordan/Falls Stormwater Load Accounting Tool and offers guidance on how developers and local governments should enter the square-footage of riparian buffers, wetlands and open water into the tool. The division asks local governments to share this memorandum with developers in their jurisdictions.
Local Government Stormwater Programs
Local Government Existing Development Inventories
In preparation for implementation of their Stage I load reduction programs, local governments were required to develop inventories and characterize load reduction potential to the extent that accounting methods allow of the following by January 2013:

Falls Lake Agriculture Watershed Oversight Committee (WOC)
The purpose of the Watershed Oversight Committee (WOC) is to guide the implementation of the Agriculture Rule. This committee is charged with developing tracking and accounting methods for nitrogen and phosphorus loss from agricultural land in the Falls Lake Watershed. The Agriculture Rule was adopted in January 2011, members of the committee were appointed by the Division of Water Quality in Summer 2011, and the committee began meeting in August 2011. The WOC submitted an initial accounting report to the EMC in March 2013 followed by their first annual report in January 2014. Copies of these reports are provided below:
NCDOT Falls Lake Stormwater Management Program
The Falls Lake nutrient management strategy requires NCDOT to develop and implement a Stormwater Management Program for all new developmentand existing development activities. The NCDOT Stormwater Management document was approved by the January 2014 EMC. It describes NCDOT’s Stormwater Management Program for New and Existing Development, which addresses nutrient runoff from new and widened roads, new non-road development, and existing road and non-road development in the Falls Lake Watershed.
