This practice will be maintained for a minimum of ten (10) years.5. Component parts that are eligible for 60% cost share: a. Seeds, stolens, sprigs or sod e. Installation of materials (1 - 3)XIII.WQ 21 - Stream Crossing1. Definition A travel-way constructed across a stream to allow livestock, equipment, or vehicles to cross with minimal disturbance to the stream ecosystem.2. Purpose Prevent or minimize water degradation from sediment, nutrient, and organic loading. To protect the water course from degradation and adverse hydrological impacts. To protect the land from streambank erosion. To provide a means for animals, equipment, or vehicles to cross a water course.3. Where applicable This practice applies to all land uses where an intermittent or perennial water course exists, and livestock are currently crossing the water course.4. Policies: 1. The structure shall be maintained for a minimum of ten (10) years.5. Specifications NRCS Specification No. 728 will be used.6. Component parts that are eligible for 60% cost share: a. Earth moving - fill and excavationb. Pipe and appurtenances d. Stone, mulch or gravel g. Installation of materials (1, 2, 3, & 4)XIV.WQ 22 - Chemical Container/Used oils-Lubricants Recycling1. Definition Recycling chemical containers, used oils and lubricants so as to reduce pollution of water, land or air.2. Purpose Provide an incentive for landowners or land operators to properly dispose of chemical containers used oils and lubricants in a manner that will prevent degradation of natural resources.3. Where applicable All agricultural lands.4. Policies: a. A one-time per year credit will be allowed for the proper disposal of chemical containers, used oils and lubricants.b. The credit will be based on the cost of transportation one-way to a disposal area.c. A credit of 36.5 cents per mile will be given.d. This credit can only be used as match towards another cost shareable BMP applied by the landowner or land operator.XV.WQ 23 - Cattle Feed and Waste Management Facility1. Definition A facility to allow for the feeding of cattle in a manner that will allow for the collection, storage, and proper utilization of animal waste.2. Purpose Prevent or reduce the pollution of water, land or air by animal wastes.3. Where applicable This practice applies to areas on farmland where animal waste from the farm constitutes a significant pollution hazard.4. Policies: a. This practice is designed to provide a facility for the collection and storage of cattle waste in order to permit the recycling of waste onto the land in a way that will abate pollution that would otherwise result from existing cattle operations.b. Cost sharing is limited to preventing or solving the pollution problems where the cattle operation already exists and is part of a total farming operation.c. All necessary permits must be acquired before the facility is erected.d. All necessary plans, (i.e. Comprehensive Nutrient Management Plan, Waste Utilization Plan) shall be developed for the facility.e. The practice shall be maintained for a minimum of ten (10) years following the calendar year of installation.5. Component parts that are eligible for 60% cost share: a. Earth moving - including diversions, ditches or dikesb. Pipe and appurtenances d. Stone, mulch or gravel g. Pressure treated materials j. Seed or sprigs, fertilizer and lime.k. Installation of materialsXVI.WQ 24 - Well Decommissioning1. Definition The sealing and permanent closure of a water well no longer in use.2. Purpose Prevent entry of vermin, debris, or other foreign substances into the well or well bore hole; eliminate the physical hazard of an open hole to people, animals or farm machinery; prevent entry of contaminated surface water into well and migration of contaminants into unsaturated zone or saturated zone; prevent the mixing of chemically or physically different ground waters between separate water bearing zones.3. Where applicable This practice applies to any drilled, dug, driven, bored, or otherwise constructed vertical water well determined to have no further beneficial use.4. Policies: a. This practice does not apply to wells that were used for waste disposal, or if evidence of contamination still exists. This practice does not apply to wells that contain contaminant levels that exceed state or federal water quality standards. Treatment of contamination source(s) is required before a well is decommissioned.5. Specifications NRCS Specification No. 351 will be used.6. Component parts that are eligible for 60% cost share:e.
