Mr. Hughes said due to slow business,the rock quarry has no current plans on reopening. We discussed the facility sending NC DAQ a letter requesting to rescind their air permit(note:the letter must state no diesel generator will be operated if facility becomes air permit exempt). Mr. Hughes said he will discuss with the owner and let DAQ know what they decide to do.Note: this plant is all electric. • During the inspection,the plant had a closed sign on a wire cable across the road. • Facility Contacts: no changes at this time. • Facility Description: The facility is a rock crushing operation.

As aforementioned,during the inspection,the plant was observed shut-down. i I� GEN-1 diesel-fired generator(s) with a facility-wide total power output NSPS capacity not to exceed 736 HP (549 kW electric) at any one time NESHAP The facility is all-electric. The previous permitted diesel-fired generator has been removed from site. During past discussions,the facility indicated that they did not anticipate the use of on-site generators in the future but wishes to keep the option in the permit. • Permit Conditions 2D .0501 -Compliance with Emission Control Standards: Equipment Reporting-This regulation requires that the Permittee maintain an equipment list and a plant flow-diagram of all equipment covered by the permit. The facility keeps an on-site equipment list, plant flow-diagram and keeps a copy of their air quality permit. 2D .0510 -Particulates from Sand. Gravel, or Crushed Stone Operations-This regulation requires that all fugitive process dust emissions from crushers, conveyors, screens and transfer points be reduced to a minimum. Water sprays are required on crushers for the control of particulate emissions. Fugitive dust control appeared to be adequate during this inspection. There have been no fugitive dust complaints with regard to this facility during the past five years. The plant is shut-down. Compliance with 2D .0510 is indicated. 2D .0516 - Sulfur Dioxide Emissions from Combustion Sources-the plant is all electric. Compliance is indicated. 2D .0521 -Control of Visible Emissions-During the inspection,the plant was observed shut- down. Compliance is indicated. 2D .0524 -New Source Performance Standards (NSPS), Subpart 000- The following are subject to NSPS: SS-6 (double deck screen), and the following belt conveyors: SS-9, SS-10, SS-11, and SS-14. The opacity limit for the screen and the belt conveyors are 10%. NSPS TESTING REQUIREMENT: The facility appears to be up to date on their NSPS testing(see table below). The facility is not required to perform Method 9 testing every 5 years because none of the equipment was constructed,modified or reconstructed after April 22,2008. Past EPA Method 9 Testine: The Division of Air Quality accepted the Method 9(visible emissions)tests that were performed at Stone Supply, Inc. on November 14, 2007(see files). Mr. Tom Freeman of Freeman Environmental Consulting, LLC, performed the testing. Ms.Angela Bell of the ARO/DAQ was on-site and observed these tests. The items tested include: ID No. Description Highest Average Opacity Limit Compliance Six-Minute (%) Y/N Opacity(%) SS-6 6"x 14"Tabor Double deck 0 10 Y Screen SS-9 42"Conveyor Belt 0 10 Y SS-10 24"Conveyor Belt 0 10 Y SS-11 30"Conveyor Belt 0 t0 Y SS-14 20"Conveyor Belt 0 10 Y These tests satisfy the NSPS subpart 000 testing requirement. The facility appears to be in compliance with NSPS, Subpart 000. 2D .0535 -Excess Emissions Reporting and Malfunctions—Plant is shut-down. Compliance is indicated. 2D 0540 -Particulates from Fugitive Non-Process Dust Emission Sources-This is a complaint driven regulation designed to control non-process fugitive particulate emissions from areas such as process areas,haul roads, and stockpiles. If two substantive complaints of non-process fugitive particulate emissions are received within a 12-month period concerning the facility,the facility is required to write and implement anon-process fugitive particulate emissions control plan. ARO received dust complaints on January 2,2002 and January 3,2002. DAQ staff verified that the Permittee would need to submit and implement a particulate emissions control plan. ARO received a copy of this plan on August 22, 2002. The plan, including a water truck and water sprinklers on haul roads. Observations to verify effectiveness appears to be consistent with intent of this regulation. There have been no compliance issues regarding Rule 2D .0540 during the past five years. During this inspection,the plant is shut-down and no fugitive dust concerns were observed. Compliance is indicated. 2D .I I I I -Maximum Achievable Control Technology-The facility used to operate a 305 horsepower(200 kW)diesel generator; however, it is no longer on-site. The facility has indicated that they did not anticipate the use of on-site generators in the future but wishes to keep the option in the permit. Should this facility operate generators in the future, it will be required to comply with 40 CFR 63, Subpart ZZZZ, and National Emissions Standards for Hazardous Air Pollutants for Stationary Reciprocating Internal Combustion Engines. • Record Keeping and Reporting Requirements Review: The facility keeps an on-site equipment list, plant flow diagram and a copy of their air permit. The facility has no annual, semi-annual or quarterly reporting requirement. Insignificant Sources Listing: none. • Self-propelled screening plant: A Fintec 570 self-propelled screening plant was sold and removed from this property. Five Year Compliance History The facility has no documented violations during the last 5 years. The facility has one documented Notice of Deficiency(NOD)sent to the facility on January 14, 2016 for 15A NCAC 2Q .0304 "Applications"fora late permit renewal and emissions inventory. • Stack Test Review(since last inspections none • 112(r)review: not subject to 112(r). • Compliance Assistance: none at this time. • Recommendation/Compliance Statement/Conclusion: • Recommendations: none • Conclusion/Compliance Statement: During the inspection,the facility appeared to in compliance by shutdown.
