One set of submittal coversheets for the SWPPP was not included on Thursday 3/7/2013. You were given that submittal form earlier this week. They need to be completed to include with the stormwater plan review, to clearly show that your plans include all of the submittal elements. Please submit as soon as you can to completed this review. The building permit for the silo foundations can proceed, but you need to provide the submittal checklist to the Permit Assistance Center. Use this link to download the checklist. http://www.co.mason.wa.us/forms/Community Dev/stormwater checklist doe 2005 manual.pdf If you have additional questions, direct them to me. Allan Borden The building permit for the silo foundations (COM2013-00013) has been reviewed and signed off by Larry W. (commercial plans reviewer). I have reviewed the permit application and SEPA checklist. You have provided the site plan and elevation drawing for the silos, and on Thursday March 7th, you will submit the site specific Stormwater Pollution Prevention Plan as part of the final information needed to review this permit, which I will review on Thursday March 7th. The Permit Techs can then pull the permit file to prepare to issue the permit COM2013-00013 on Friday March 8th. Allan Borden Planner- Long Range & Site Inspection P.O.

These documents will be submitted the morning of March 7. As you know this project has many moving parts to it and the issuance of the building permit is a critical path to even begin the assembly process. The foundation constructed file://C:1Documents and SettingslAhblLocal SettingslTempVPgrpwise15138C6D3Masonmai11001626A6811 DC... 3/7/2013 Page 2 of 2 for the silos requires concrete curing time. It is critical that this foundation is poured sooner than later. Given that there are several steps that need to be scheduled to complete the foundation work. I am wondering if a building permit can be issued to Granite on Friday morning March 8 so that we can move forward with the pouring of the concrete foundation. As a condition of the Sand and Gravel General Permit Granite is obligated to maintain and implement a SWPPP with discharge monitoring plans and maintenance of prescribed Best Management Practices along with quarterly reproting. I am hoping that by providing you a copy of this plan that it will alleviate your concerns with regards to managing stormwater discharged from Asphalt Plant Operations. Can the building permit be issued Friday March 8 to so that Granite can move forward with the construction of the foundation?

Date Signed NARRATIVE DESCRIPTION OF Form 11 INDUSTRIAL ACTIVITIES AND Completed by: Dana Stringer SIGNIFICANT MATERIALS Date: March 6, 2013 A hot mix asphalt (HMA) facility heats and dries a mixed sized aggregate and combines it with liquid asphalt to create an asphalt product. Various grade aggregate and RAP is stockpiled in a designated area adjacent to the asphalt plant. A front end loader loads aggregate from the stockpiles into cold feed bins which use conveyors to proportion the aggregate mix that is introduced to the propane fired drying drum. As the heated aggregate moves down the drum, recycled asphalt pavement (RAP) from another feed bin and conveyor is added through a collar on the drum. A controlled proportionate amount of liquid asphalt is mixed in near the end of the drum to coat the aggregate, forming hot mix asphalt. To make warm mix asphalt, the aggregate and RAP are heated to the lower temperature range and small amounts of water are added to produce steam and foam the liquid asphalt. The hot or warm mix asphalt moves from the bottom of the drum into a drag slat conveyor that fills a silo where it is temporarily stored. A release agent is applied to the bed of haul trucks and asphalt product is loaded into the trucks for transport. The following paragraphs address any areas where significant materials are stored or industrial activity occurs. Stockpile Area BMPs • Site is bermed to retain stormwater and sediment laden runoff into dedicated water control infrastructure. • Water stockpiles as needed to prevent wind erosion (Typical maritime climate on Kitsap Peninsula has high ambient humidity, maintaining relatively high stockpile surface moisture).

Erosion and Sedimentation Control Plan Granite Construction Company Western Washington Portable—Belfair, WA Plan Date: March 6, 2013 Prepared By: Dana Stringer (509)248-6823 NARRATIVE Site Description The site of Granite Construction Company's operations hosts a hot/warm mix asphalt production plant, which also includes the stockpiling of aggregates and RAP. The site has a generally flat topography with a downward slope of 1-2% to the west-northwest. As a previous industrial site, the ground has been cleared and shows no evidence of significant erosion. Granite's operational site is part of a contiguous 43.2 acre industrial property that is fully contained for stormwater runoff and has onsite engineered retention and infiltration. Any sediment laden water produced onsite is fully retained onsite. See "Site Map" included with the SWPPP for a detailed site layout. Planned Erosion and Sedimentation Control BMPs 1. Paved Haul Road Haul road to and from silos will be paved to prevent creation of track-out or removal of sediment from the site onto adjacent properties. Road will be wet swept as needed to prevent track-out. 2. Gravel Top Layer Exposed soil with a slope or in operating areas will be graveled to prevent the creation of mud, heavily sediment laden water, or track-out from aggregate delivery trucks. Gravel will also minimize creation of dust and sediment erosion transported by wind. 3. Diversion Berms and Conveyance Diversions berms will be constructed around entire operational area to prevent sediment laden water from leaving the site. Stormwater will also be prevented from sheet flowing onto site and contacting soils. Water will infiltrate into the ground(site has 1-2% slope so sheet flow runoff is minimized) or flow to vegetation lined ponds (BMP #4) before being conveyed to onsite infiltration area. 4. Vegetation Lined Ponds Stormwater will enter vegetated ponds to minimize sediment entering onsite infiltration area. Ponds will be vegetated with grass to slow flow of water and prevent additional turbidity.Any water leaving the ponds is conveyed to the onsite infiltration area and does not leave the site. 5. Quarry Shall Protection of Pipe Outlet The outlets of the pipes conveying water from the ponds,under the haul road,to the catch basins will be armored with spalls to prevent erosion. 6. Land Gradins The near level and 1-2% slope of the site will be maintained to prevent sheet flow and erosion. 7. Watering of Stockpiles and Roads Stockpiles and roads will be watered as needed to prevent the creation of dust and wind transported sediment. The maritime climate of the site maintains a relatively high humidity in the air and ground surfaces. 8. Retention Pond All water leaving the bermed operational site of the asphalt plant is conveyed to an onsite infiltration area. Any sediment in the water is retained onsite at this point. Inspections and Maintenance plan At a minimum, all ESC BMPs will be inspected: • Weekly and after any measurable rain event(0.5 inch or greater) between April 1st and September 3 1". • Daily and after any measurable rain event (0.5 inch or greater) between October 1 Sc and March 3 1". Deficiencies identified during the inspection will be corrected within 24 hours or as directed by the Environmental Coordinator. In addition to the above inspections, the ESCL will supervise Belfair Asphalt Plant personnel to ensure the following: • Sediment will be removed from the pre-catch basin ponds when the ponds no longer drain properly. If grass cannot be maintained due to site conditions, spalls will be placed to line ponds. • Any needed repairs or improvements will be brought to the attention of the ESCL, who will take appropriate steps to implement such repairs or improvements. • Any runoff leaving the site during storms will be noted, and turbid water conditions checked for. • Any additional BMPs needed to address site-specific erosion control will be implemented. • Streets surrounding the site will be inspected for any dirt tracking. Any unusual or problematic discharge of dust,particularly during dry periods, will be noted. The ESCL will take appropriate steps to implement repairs, improvements, or additional BMPs to address any issues that might be noted.
