At the Seneca II-W Mine, there are approximately 2.1 miles of existing and proposed light use roads. Light-use road locations are shown on Exhibits 12-2, 12- 3, 13-2, and 13-2A, and a typical cross-section is presented on Figure 13-6. These roads are only used on an intermittent basis for purposes other than transportation of coal, including but not limited to, roads used for monitoring and periodic maintenance of monitoring facilities and reclaimed areas. With the acceptance of Stipulations 32 and 35, the operation is in compliance with the requirements of this section. II. Support Facilities -Rule 4.04 Support facilities used in conjunction with the Seneca II-W Mine include an equipment construction site, fuel storage areas, an equipment shop, office/bathhouse, a potable water well and supply line to the approved facilities area, an electric substation and an explosive storage facility, and Sediment Ponds 005, 006, 009, 015, 016, 016A, and 017. Volumes 7-9, Tab 13, contain detailed information on [he existing and proposed mine facilities. III. Hydrologic Balance -Rule 4.05 A. Water Quality Standards and Effluent Limitations Storm runoff from all disturbed areas (except some topsoil stockpiles), pit ptunpage, water treatment facilities, and spoil springs will pass through a sediment pond designed to ensure that all discharges meet effluent limits in Seneca Coal Company's NPDES permit for the Seneca II-W Mine. A storm water permit and spill prevention containment and control plan associated with the NPDES permit also dictate preventative and mitigation measures for ensuring that all water leaving the mine site meets applicable effluent limits. Disturbed areas, as defined by Rule 1.04(36), are delineated on permit area map Exhibits 20-1 (original permit area) and amended Exhibit 20-1A (south extension area). The Division requested certain modifications to Exhibit 20- lA during the PR-4 review, that have not been provided. In a letter of 7uly 7, 2004, the Division noted that the exhibit had not been certified by a qualified, registered professional engineer or professional geologist in accordance with Rule 2.10.3(2). In addition, the Division pointed out that certain areas that would appear to meet the definition of "disturbed" had not been included within the delineated disturbance area on amended Exhibit 20- lA. Specific areas noted include the slide disturbance on the steep slope east Seneca II-W Findings Document 22 November 17, 2004 Petmi[ Revision No. 4 of the ridgeline pit in the Pond 015 watershed, and the road that accesses Topsoil Stockpile AAA. In addition, the Division requested that ephemeral drainages that will convey concentrated disturbed runoff from areas of active mining or reclamation in the Pond 015 and Pond 017 watersheds be delineated as disturbed or potentially disturbed. This request is due to the potential that exists for sediment deposition or erosion within such drainages. The following stipulation is warranted.
