INSPECTION OBSERVATION/COMMENTS: On March 27,2019 a compliance assurance visit was conducted
by myself,Samantha Mellott,Environmental Specialist with the assistance of Lloyd Tyson, Plant Manager.Mr.
Tyson provided their environmental notebook that included copies of the facilities' rescinded air permit,permit
rescission letter(sent October 6,2016),and all of their maintenance and production logs.The facility produced 5866
cubic yards of concrete in 2017 and 5347 cubic yards in 2018.
Mr.Tyson walked me around the property and explained that since they are still in their slow season only one truck
was loaded earlier in the morning and he wasn't expecting any more before lunch.I did get the opportunity to watch
a tanker truck blow cement into the silo. It was explained that the facility does wet down the yard when necessary to
control any dust during a dry day.
All equipment appeared to be well maintained.The baghouse is inspected monthly with the most recent inspection
occurring February 13,2018. Mr.Tyson stated that he expects another inspection to occur sometime soon,if not that `
same day.All of the bags are typically changed every 5-6 years with the most recent complete change occurring
June 7,2018.
No dust, odor,or visible emissions were observed at the time of the visit.
REGULATORY REVIEW:
2D.0515"Particulates from Miscellaneous Industrial Processes"
The allowable emission rates for particulate matter from any stack,vent,or outlet,resulting from any industrial process for
which no other emission control standards are applicable, shall not exceed the rates as outlined in this regulation.
The facility demonstrates that they practice proper operation and maintenance of their sources and it is reasonable to expect
that they do not exceed allowable emission rates. Compliance is indicated
2D.0521 "Control of Visible Emissions"
Visible emissions(VE)from permitted sources shall not be more than 20%opacity when averaged over a six-minute period.
The facility was not operating at the time of the visit so no VE was observed.There have been no complaints regarding VE
since the time of last compliance assurance visit. Compliance is indicated
i
2D.0535"Excessive Emissions Reporting and Malfunctions"
There were no indications of equipment malfunctions that would result in excessive emissions requiring more than four hours
to repair.No such reports have been submitted since the time of last compliance assurance visit.Compliance is indicated
