NRCS Practice Standard: Roof Runoff Structure (558)
About the Company:
The Natural Resources Conservation Service (NRCS) is the US Department of Agriculture (USDA)’s primary private lands conservation agency. The NRCS helps producers protect and conserve natural resources on private lands through voluntary conservation programs. Through Practice Standards and technical guides, the NRCS provides information about the conservation, energy resources, and provides personalized advice to individual producers.
The NRCS’ Environmental Quality Incentives Program (EQIP) provides technical and financial assistance to producers as they implement NRCS Conservation Practice Standards.
Technical guides used in each field office are localized so that they apply specifically to the geographic area for which they are prepared. Thus, while national guidelines have been provided as a framework for each standard, each state has adopted and modified the conservation practice standards to suit their individual landscape.

About the Solution:
Roof Runoff Structure (558)
A roof runoff structure is a structure or system of structures to collect, control, and convey precipitation runoff from a roof.
The practice applies where roof runoff from precipitation needs to be diverted away from structures or contaminated areas. Roof runoff water that becomes contaminated by contact with animal waste must be stored and then transported to the field for land application. Diverting clean water away from animal waste concentration areas reduces the amount of liquid that must be stored and utilized.
Collecting the runoff and transporting it to a stable outlet also reduces soil erosion caused by runoff, and improves water quality.
Roof runoff water can also be collected and used for other purposes. Non potable water can be used for irrigation. Potable water storage structures must be constructed of materials and in a manner that will not increase the contamination of the stored water. Roof runoff that is collected and stored for potable use must be treated prior to consumption. It must be tested periodically to ensure that adequate quality is maintained. The use of roof runoff water for livestock water must be evaluated on an individual basis. Components of this practice can include gutters, downspouts, rock-filled trenches or pads, and subsurface drains or outlets.
This practice has a minimum expected life of 15 years. Roof runoff structures must be kept clean and free of obstructions that reduce flow. Maintenance requirements include regular inspections and repair of damaged components.
Common Associated Practices
NRCS Conservation Practice Standard (CPS) Roof Runoff Structure (Code 558) can be applied to new or existing roofs. It is commonly applied with other conservation practices, such as:

Solution Strengths, Weaknesses and Critical Indicators
NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.
General Support & Other:
- Can be an integral part of many manure management systems
- Most projects have at least some equipment that supports operations of the main technology
- This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.
Newtrient is using the USDA-NRCS conservation practice standards as tools to assist dairy producers in understanding the standards and how they can be used to address resources concerns.
To establish a Practice Standard a system or practice must be thoroughly vetted, approved, and standardized by the USDA at the federal and state level. These conservation practices have been developed to address various environmental resource concerns. Newtrient has developed a 9-point scoring process for ranking additives, practices, services, and technologies for the dairy industry. Recognizing the rigorous approval procedure used during the development of the NRCS Practice Standards, many of them score very highly and are worthy of consideration on any dairy where they apply.
The information provided here is a summary of the selected conservation practices. For up to date and detailed information related to the full Practice Standards, please see the USDA NRCS website, linked above.
