2. Temporary stabilization - <br />a. For areas where final grading or surface disturbance has been <br />completed but 1) temporary or permanent seeding cannot be <br />immediately established due to seasonal planting limitations or 2) that <br />will be constructed on within 12 months, either one or a combination <br />of the following practices will be employed: <br />i. The surface will be roughened; <br />ii. A mulch, such as crimped straw, wood chips or hydro - mulch, <br />will be applied ; or <br />iii. A tactifier will be applied. <br />These areas will be monitored to assess if additional measures will be needed <br />during the interim period. <br />b. Areas that are projected to not be constructed on within 12 months but <br />will be completed within 24 months will be re- vegetated with a <br />temporary vegetative cover; such as an annual grass or cereal grain. <br />These newly seeded areas will be protected by mulch, i.e.; such as <br />hydro -mulch or crimped straw. <br />3. Permanent stabilization — Areas where final grading of surface disturbance <br />have been completed will be stabilized by either one or a combination of the <br />following methods: <br />a. Drill seeding, hydro- seeding and /or hydro - mulching; <br />b. Permanent vegetation — native plants; <br />c. Mulch — wood or straw; <br />d. Sod <br />e. Soil retention blankets (SRB) <br />f. Outlet /drainage protection — riprap or rock <br />Hydro -mulch consisting of wood cellulose fibers will be mixed with water and a tactifier <br />agent and applied at a rate of no less than 2,000 pounds per acre with a hydraulic <br />mulcher. <br />Straw mulch will consist of clean, weed free straw. The straw will be applied at a rate of <br />approximately two tons per acre and will be anchored mechanically by crimping or with <br />the aid of tactifiers. Anchoring by crimping will be the preferred method for all areas <br />with a slope equal to or less than 3:1. <br />All of the above seeding criteria are subject to change and approval by the Colorado <br />Division of Reclamation , Mining and Safety representative. <br />Animas Glacier SWMP February 2012 <br />p. 12 <br />
