NRCS Practice Standard: Pond Sealing Or Lining – Geomembrane or Geosynthetic Clay Liner (521)

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:

Pond Sealing Or Lining – Geomembrane or Geosynthetic Clay Liner (521)

Pond sealing or lining is the installation of a liner for a pond or waste impoundment consisting of a continuous synthetic flexible material.

Practice Information

The purpose of this practice is to control seepage from water and waste impoundments for the purposes of water conservation and environmental protection. This method of pond sealing is relatively expensive, but often necessary for sandy textured sites and projects that require a very effective sealant.

This practice applies on ponds and waste storage structures that require treatment to control seepage rates within acceptable limits, and to prevent the migration of contaminants offsite. Subgrade materials must not contain sharp, angular stones or any objects that could damage the liner or adversely impact its function.

Operation and maintenance required for this practice include periodic inspection of the visible portions of the liner for tears, punctures, or other damage; and monitoring the liquid level in the structure for the design capacity.

Common Associated Practices

Conservation Practice Standard (CPS) Pond Sealing or Lining - Geomembrane or Geosynthetic Clay Liner (Code 521) is commonly applied with other conservation practices such as:

  • Irrigation Reservoir (Code 436)
  • Pond (Code 378)

    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 Comments/Opinions:

    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.
