Additional Page 2004 Annual Report Winkler Light Aggregate quarry M-1989-065 Centennial Materials, Inc. Anniversary Date: April 26 Overview of Permit Year: During the 2003/2004 operating year there was about the same amount of activity at this site as occurred during the last couple of years. Most of the operation remains much as it was last year. The small northward expansion of the Main Quarry that occurred last year was completed and much of that was backfilled in 2003. A new mining area of about 2 to 3 acres was established. There was limited activity at the Cut Stone Quarry portion and that disturbance remains rather small and essentially identical to last year. One additional small shot was done on the west, but the increase in area is so small it is not actually definable on the map. Annual Report Maps: Enclosed axe four color maps showing the primary areas of disturbance and the type of disturbance occurring in each area. Map 1 shows the entire site and is primarily a guide map. Map 2 includes the Cutstone portion and Maps 3a and 3b show the information for the Main Quarry area. Affected Lands: The amount of affected land increased slightly to about 94 acres. However, 5.1 acres has been successfully seeded and approximately one acre was backfilled. More backfilling will occur in the 2002/2003 mining area during 2004, followed by topsoiling and seeding. For the most part, the operation seems to have achieved the stable operating area. It appears that this stable area, fox now, will vary between about 80 and 95 acres, including the significant amount of acreage in the access road. Fox the foreseeable future the amount of land reclaimed will approximately balance the amount mined, but that balance will be visible only over a 12 to 18 month cycle as new reclamation is necessarily out of phase with new mining. That is, increases in reclamation area lags behind increases in mining by about 6 to 9 months with xevegetation lagging about 9 to 14 months due to the fact that seeding can only occur during two fairly narrow windows each year. In between backfilling and seeding topsoiling is done. If viewed at any one time, it may appear that mining is moving ahead of the reclamation and, at other times, reclamation is increasing and the mining declining. It all depends on what point in the cycle the site is examined. A significant portion of the total affected land is contained in the access road. The Cut Stone portion amounts to about 5 acres, including the access road to that site. The remainder is involved in the main quarry operation, stockpiles, and office area. The plant remains located down in the quarry hole. The stockpiles are now generally kept in the quarry hole, but some stockpiling is done near the plant, as is usually the case. Revegetation: In the main quarry area, 5.1 acres were seeded in 2002. Considering the severity of the drought in 2002, it is amazing that the seeding was as successful as it was. In 2003 this seeding appeared to only be partially successful, but between 2003 and 2004 the cover and vigor of the planting increased considerably. Although questions existed previously as to whether the seeding would ultimately achieve the desired cover, that question is now largely answered in the affirmative. Weed control was implemented at various locations along the access road and was largely successful. Grass along the road appears stronger this year due to better growing conditions and decreased competition from weeds. Additional weed control will be done in a few places where weeds axe still a problem. Some weed control will be implemented in the new xevegetation area.
