Since the tops %l seed bank may not provii tan adequate number of seedstl`to revegetate redistributed' soils, leveling of redistributed soil will likely be followed by the seeding of species commonly used in the revegetation of disturbed ' lands. A prototypical seed mix and drill seeding rate recom- mended by the Soil Conservation Service include Blando, brome at 15 pounds per acre and an inoculated legume - either Cali- fornia bur clover (Medicago luspeda) at 5 pounds per acre or Lana vetch (Vicia dasycarpa) at 8 pounds per acre. Broadcast seeding on pit wall slopes and other areas will be conducted at higher rates. The recommendations in publication CA342, concerning critical area planting, will be used in conjunc- tion with other SCS recommendations and information regarding new cultivar releases, fertilizer formulas, etc. , to deter- ' mine seeding, fertilizing, and mulching operations. Seeding is planned for the fall, roughly the period September 15 to November 15, to maximize success potential. We 'intend to withhold grazing during the first year until seed set, to insure an adequate supply for the next growing season. Similarly, tree plantings (seedlings or acorns) will be afforded protection from grazing until mature enough to survive in a grazing environment. Several prospective tree planting sites are available, including reclaimed and undis- turbed areas. The quarry operator will continually monitor reclaimed areas I to assess the degree of reclamation success and the need for f the application of corrective measures such as soil amend- ments, erosion control, or adjustments to the reclamation I ` plan. Monitoring shall include reconnaissance for noxious ! weeds. The Agricultural Commission office' s "Noxious ,'Weed Control Plan for Grading and Quarry Excavation Permit Sites" will serve to guide monitoring, identification, and treatment ;. exercises for known or suspected noxious weeds. The plant facilities will be reclaimed upon completion of excavation operations or earlier if their utility has ex- Aired. All segments of the processing facilities will be dismantled and removed from the site. Various spare parts, materials, supplies, and refuse will also be removed from the j site. The office/shop building may remain; it may be useful for various agricultural purposes. Processing pond embank- ments will be graded to the extent necessary to blend the dry sediment bed with the surrounding landscape. Culverts and pipes will be removed from temporary roads, and roadbeds and ditches will be recontoured to conform to adjacent topogra- phy. Topsoil will be placed on the reclaimed portions of the plant facilities. Exhibit 7, "Reclamation Plan" , shows the proposed final topography less projected topsoil and overburden depths of 1 " to 3 feet. This is based on a drilling program that was i conducted to establish the estimated quarry floor. �LL F . 3 KRC Aggregate, Inc. 1i - 9 - April 1, 1994
