Rangeland is the most extensive land type in California, more than 40 million acres of the state's 101 million acres with about one-half (20 million acres) in private ownership (but representing 90% of the forage base for the state's range livestock). Eight of California 12 major drainage basins are dominated by vegetation types that are commonly grazed. The precipitation that falls on California rangeland represents only about 15% of the total surface water source (7-9 million acre feet), but the location of rangelands between the forested areas and major river systems means that almost all surface water in California passes through rangeland. In addition, two-thirds of the major reservoirs are located on rangeland. The quality of California's surface waters is, therefore, greatly influenced by the hydrology of rangelands. Erosion assessments in California estimate erosion averages of 3l3 tons/acr/yr from sheet and rill erosion on one-third of private rangelands, while streambank erosion is another potential source of sediment on over 9,000 miles of streambanks.
The California Rangeland Water Quality Management Plan (CRWQMP) was approved by the State Water Resources Control Board in July of 1995. This plan, developed by industry, conservation organizations, and state and federal agencies describes a program of voluntary compliance with the Clean Water Act, and Porter-Cologne Act.
In late 1989, California's Range Mangement Advisory Committee (RMAC) to the State Board of Forestry, made up of livestock industry and public members, identified water quality as a priority issue. This resulted in two mutually reinforcing activities that have increased awareness of clean water issues among private rangeland owners:
In 1990, leaders in the livestock industry began working with RMAC and the State Water Resources Control Board (SWRCB) to develop a rangeland water quality management plan. A technical committee was formed by NRCS, UCCE, the California Department of Forestry' Forest and Rangeland Assessment Program and the SWRCB. This technical committee under the leadership by UCCE and NRCS outlined the plan and began to compile technical information on ranch and watershed planning, management practices, and monitoring for inclusion in the plan.
In 1993 AGvocate, a private consulting firm, was hired to coordinate a concentrated two-year effort to complete the plan. AGvocate compiled information on agency roles and responsibilities, policy and coordination mechanisms, sources of funding, and technical assistance. The firm worked with an advisory committee that included industry, agency, and environmental interests to help review and develop the California Rangeland Water Quality Management Plan (CRWQMP). During 1994, 18 input meetings were held with industry and agencies to seek input on the plan.
In 1994, the plan was accepted by industry organizations. In early 1995, RMAC approved the plan, and in July 1995, the State Water Resources Control Board approved the plan.
With approval of the California Rangeland Water Quality Management Plan, the SWRCB, the livestock industry, and rangeland owners and managers must now implement this plan and prove that voluntary compliance is a viable alternative to regulatory prevention of nonpoint source pollution. The CRWQMP provides for three approaches to voluntary compliance:
Where water quality issues are minimal and/or a management strategy is in place, a letter of intent may be written and filed either at home or with the local Resource Conservation District office. This letter should include brief paragraphs on the evaluation of water quality status, management approach being implemented, and the monitoring program for continuing evaluation. It will be a document to use if and when water quality issues arise. In some cases, landowners/resource managers may wish to file this letter with the local office of their Regional Water Quality Control Board.
Where a written plan is desired, it does not have to be lengthy or complicated but should include the following elements.
This management strategy should be ongoing, with evaluation and revisions as needed.
Many landowners have a desire for some form of institutional recognition of their planning and implementation efforts, as well as legal support against potential nuisance complaints. There are currently two methods available that would provide for a Nonpoint Source Management Plan to be recognized as utilizing acceptable standards and practices that affected agencies will recognize and support.
Voluntary compliance is the first of three options for achieving water quality goals. If voluntary compliance is unsuccessful the Regional Water Quality Control Boards (RWQCB) have the authority to invoke the more stringent options.
Regulatory-Based Encouragement of Management Practices: This option will set water quality standards or goals (management measures) but will not prescribe specific practices. Regional Boards may encourage management practices by waiving adoption of Waste Discharge Requirements on condition that dischargers comply with management practices. While management practices may be left up to the landowner, a ranch water quality plan may be required by the RWQCB. Regional Boards may also enter into agreements with agencies that have management responsibilities for publicly owned or controlled lands. Once management practices have been formally approved by the State or Regional Board, they will become the primary mechanism for meeting water quality standards.
Effluent Limitations: Regional Boards will adapt and enforce Waste Discharge Requirements on proposed or existing nonpoint sources of pollution. Regional Boards are precluded from specifying the manner of compliance with waste discharge limitations. However, limitations may be established at a level that, in practice, would require implementation of appropriate BMP's.
