Which of the following references provides technical guidance for implementing runoff requirements?

The reference provided for implementing runoff requirements is the EPA Technical Guidance. The Environmental Protection Agency (EPA) develops and provides a wide range of guidelines and resources related to stormwater management and runoff control, emphasizing the importance of minimizing water pollution and managing water resources sustainably. Their technical guidance often includes information on best management practices, case studies, and standards that can be beneficial for projects aiming for compliance with LEED standards regarding stormwater management.

The other options, while they may provide valuable information in their respective areas, do not focus specifically on technical guidance related to runoff requirements. USDA Guidelines are primarily concerned with agricultural practices, Department of Energy Reports focus on energy efficiency and conservation measures, and National Park Service Directives pertain to the management of national parks and protected areas. Only the EPA's resources specifically address the challenges and methodologies associated with managing stormwater runoff effectively.
