2 . <br /> s 3 . Location and Number of Acres in Various Stages of Reclamation <br /> p Vegetation is developing on the 51 acres of the old dump site , <br /> and on approximately nine acres in Cuts 1 and 2 . The approxi- <br /> mately 30 acres of Cut 3 has been backfilled, and is scheduled <br /> for top-soiling and seeding in 1988 . <br /> 4 . Species of Vegetation Planted, the Location and Dates of Planting <br /> No new seeding was done in 1986 . See 1985 Annual Report for <br /> the seed mix used in presently developing areas . <br /> 5 . Type and Approximate Quantity of Fertilizers , Organic Material, <br /> or Soil Conditioners Used and Location of Use . <br /> No fertilizers or soil conditioners were used this year, however , <br /> application has been made for a permit to use sewage sludge from <br /> the Fremont Sanitation District . <br /> 6 . Appraisal of Results of Reclamation Efforts <br /> Areas seeded to grasses continue to develop . More trees have <br /> been transplanted by a different technique , and appear to be <br /> surviving. <br /> 7 . Estimates and Location and Number of Acres to be Affected in the <br /> Coming Year . <br /> No new disturbance is scheduled for the 1986-87 year . <br /> S . The effective date of the information provided above , and as <br /> outlined on the included map , is October 1 , 1986 . <br /> 9 . A new system of dust disposal is being implemented . Beginning <br /> in 1987 , waste dust will be trucked from the plant and deposited <br /> in conjunction with the overburden strippings in the active <br /> backfill areas . The volume of dust is projected to be approxi- <br /> mately 87 , 000 yd3 to be deposited with 1 . 9 million yd3 of <br /> overburden in 1987 . The ratio of dust to overburden is projected <br /> to be less than 5% . The dust will be dumped down the backfill <br /> face which normally measures 80-100 feet in elevation, thus <br /> most of the dust will be deeply buried in a short period of <br /> time , and wind erosion controlled . The surface will then be <br /> topsoiled and revegetated in the normal sequence of reclam- <br /> ation . The waste dust is classified as a non-hazardous waste . <br /> This is a formal request for a Technical Revision to Permit <br /> No . 77-344 , to incorporate the waste dust from the plant in <br /> the backfill of the mined-out areas of the Portland Quarry. <br /> Paul E .
