e 2. A Nxtionat Pollutant Discharge Elimination System (NPDES) permit, administered by the US Environmental Protection Agency and/or Washington State Department of Ecology, will be req�ired for clearing and grading activities on this site if the site area disturbed by land alteradon activities �s greater than or equal to 5 acres. 3. A Notice of Construction must be obtained from the Puget Sound Air Pollution Control Agency. MITIGATION OF ADVERSE IMPACTS BY SEPA 1. The approved site plan associated with SEPA No. 491 is superceded by this approval. To the extent that changes to the site plan on Lot 2E of Seaway Center generate conflicts with the SEPA No. 4-91 site plan as applie� to other lots in Seaway Center, those conflicdng aspects of the SEPA No. 4-91 site plan are Null and Void. Prior to final approval of this MDNS, the Responsible O�cial must receive written acceptance of this condition from by representatives of all owners of interest in the Seawxy Center lou covered under SEPA No. 4-91. (SEPA Land and Shoreline Use Policies.) 2. Any grading/fill on this site shall be done so as to not impact the surrounding properties. (SEPA Earth, Land and Shoreline Use Policies.) 3. A tra�c study must be submitted before building permits are issued to determine trip generation, driveway sight distance, and driveway locations. If relocation of the driveways results in a significant re-design of the s�te, additional SEPA review may be requ'ved. (SEPA Transporcation Policies) 4. Shued driveways are required with adjacent properties unless topography or serious operational difficuldes make shared driveways mfeasible. Access easements from the Cintas driveways to Lots 2D and 2F must be provided in locations approved by the City Engineer. (SEPA Transportation Policies) 5. A transportation demand management program must be approved and in place before occupancy will be granted. (SEPA Transportation Policies) 6. A transit information display in the lobby/entrance area, or other cenUal location is required. This display must provide transtt schedules, car/vanpool information and a list of ridematch serv�ce phone numbers. (SEPA Transportation Policies) � Previous approvals called for routing a small flow of water into the native growth areas at the rear (western portion) of the site. The quantity of flow and discharge location(s) must be chosen to ensure that erosion of natural areas wili not occur becween the dischazge point and the main branc:h of Powder Mill. Appropriate downstrcam analysis wiil be reyu�red to demonstrate that this requirement is being met. The analysis must be reviewed and approved by the City prior to issuance of construction perm�ts. (SEPA Water and Earth Pol►cies) 8. Provided the peak sewer discharge rate is limited to the 0.34 cfs indicated in the March 15, 1994, Barghausen Engineering, Inc. letter, the existing sewer s�stem can accommodate the required sewer flow. However, this water intensive use wasn't anticipated when the sewer system was designeci for the area. Therefore, the balance of ihe Seawa� Center site will need to be developed with a sewer usage consistent with the design cntena of 4,000 gallons per acre per day.
