City. In Siler City,turn left onto Greensboro Avenue and follow Greensboro Avenue until it tees into North Second Avenue.Turn left onto

(I1) FACILITY DESCRIPTION: Chandler Concrete Company,Incorporated=S'iler City Plant#T09—is a concrete batch plant.-This
facility was made permit exempt in a letter.dated September 23, 2016, with the exemption based upon a limitation not to exceed five
hundred thousand (500,000) cubic yards per consecutive twelve (12) months running average. Based upon the application review
spreadsheet calculations,five hundred thousand(500,000)cubic yards of concrete would be approximately one hundred sixteen(116)times
greater than this facility has ever produced during the past five(5)years.
(III) SPECIAL SAFETY NEEDS: Personal Protective Equipment(PPE)includes,but is not limited to: 1).hard hat;2).high
visibility/reflective safety vest;3). safety shoes/boots;4).hearing protection,and 5). safety glasses.
(IV) INSPECTION SUMMARY: On March 4,2020,I(Jeff Bouchelle),conducted a Compliance Assurance Visit(CAV)at
Chandler Concrete Company,Inc., Siler City—Plant 109. Mr.Kenneth Waegerle,Corporate EHS Manager,was my contact for
this visit. I observed the plant to be in a good working order. All fittings appeared to be tight,with no leaks around the
batching/load-out areas. General housekeeping around the facility grounds also looked to be kept neat and orderly. Baghouse
records for the fly ash/cement are being checked on a regular(weekly)basis for: housing exterior;door and door gasket;shaker
drive and motor;belts;bearings; shaft;bag straps;and the number(if any)bags needing replacing. Total throughput for calendar
year 2019 was 3,433 cubic yards of concrete. Total cubic yards of concrete(produced)over the last several years have been well
below the modeled limitation of 500,000 cubic yards. Five hundred thousand cubic yards(or less) is the amount of concrete
(produced)to remain permit exempt(PM-10 emissions<5 tons/consecutive 12 months).
(V) CLEAN AIR ACT SECTION 112(r)REQUIREMENTS: Pursuant to 40 CFR Part 68,if the Permittee is required to
develop and register a Risk Management Plan(RMP)pursuant to Section 112(r)of the Federal Clean Air Act,then the Permittee is
required to register this plan to the EPA.
RMP Not Required—Chandler Concrete Co.Inc.,is subject to the 112(r)program general duty clause,but does not maintain
regulated chemicals onsite above the threshold quantities,which would require a risk management plan.

■ July 25,2016—A Notice of Violation(NOV)was issued for failing to submit the 2015 annual report. .
• April 4,2014—A Notice of Violation(NOV)was issued for failing to submit the required 2013 annual report.
