Annual CCRFugitive Dust Report Sooner Generating Station SECTION 1- INTRODUCTION This documentis intended to fulfill the requirements for an Annual Coal Combustion Residuals (CCR) Fugitive Dust Control Report (Annual Report) established in 40 CFR Part 257.80(c). The Annual Report summarizes the activities as described in the Coal Combustion Residual Fugitive Dust Control Plan (CCR Dust Plan) and includes a description of actions taken to control CCR fugitive dust, a record ofall citizen complaints, and a summary of any corrective measures taken. SECTION2- FUGITIVE DUST CONTROL METHODS The following fugitive dust control measures were implemented during the period covered by the Annual Report: 2.1 Fly Ash 2.1.1 Precipitator Hoppers Dust from hopper maintenance was minimized by emptying the hoppers as completely as possible before opening hatch doors. Ash removed from the hoppers was properly disposed, Clean up methodsutilized by personnel included the use of skid-steer loaders, vacuum trucks, shovels, and brooms. 2.1.2 Fly Ash Silo The fly ash silos are equipped with vent systemsthat discharge into the precipitators to prevent the emission of fugitive dust. The silos feature telescoping discharge piping allowing for a zero drop distance when loading trucks. The discharge piping is equipped with a vent system to capture dust during loading. Trucks loaded with ash were enclosed. Fly ash that accumulated at the base of the silos was removed or watered when the possibility of fugitive dust existed. 2.1.3 Fly Ash Storage Building The Fly Ash Storage Building is enclosed to preventfugitive dust. The truck loading system has a movable discharge pipe to lower the drop distance of materials. The discharge piping is equipped with a vent system to capture dust during loading andreturnsthe dust to the building. Trucks loaded with ash were enclosed. Any spillage of material from this operation was managed by Evans and Associates Construction Co., Inc. as they occurred to mitigate fugitive dust.

Since bottom ash is sluiced with water to the dewatering bins it is normally a wet material with little to no fugitive dust impacts. Bottom ash that accumulated atthe base of the dewatering bins was removed or watered when the possibility of fugitive dust occurred. Trucks loaded with ash were properly tarped when the opportunity for fugitive dust existed. 2.3 Economizer Ash Economizerash wasstored in an enclosed silo. Thesilo features a telescoping discharge pipe allowing for a zero drop distance when loading trucks. The discharge piping is equipped with a vent system to capture dust during loading. Trucks loaded with ash were enclosed or properly tarped ifthe opportunity for fugitive dust existed. Ash that accumulated at the base of the silo was removed or watered when the possibility of fugitive dust existed. 2.4 Non-marketable Ash Non-marketable ash was disposed ofor moved to the ash staging area. Clean up methods utilized by personnel for non-marketable ash included the use of skid-steer loaders, vacuum trucks, shovels, and brooms.If necessary, water or tarps were applied to non-marketable ash to prevent fugitive dust. 2.5 Ash Staging Area The ash staging area has a concrete base and walls that act as a partial wind break. The area was watered if necessary to control dust. Non-marketable and bottom ash material stored in the staging area was loaded into open top trucks with front end loaders and was transported offsite for either beneficial use or disposal. Trucks loaded with ash from the ash staging area were properly tarped when the opportunity for fugitive dust existed. 2.6 Roads and Drive Areas When necessary, watering and the removal of excess ash material was used to suppress dust on roads and drive areas. Additionally, the plant has posted speed limits. SECTION 3- CITIZEN COMPLAINTS There were no citizen CCR dust complaints reported during the period covered by this report.
