1. Facility Overview
Discuss ion/Introduction
On March 11,20211 arrived at the site to verify that the facility is not in operation. The gate at the entrance was
padlocked and it did not appear that there had been any recent traffic on the driveway. According to letters, annual
reports,and recent inspection reports,the facility has not operated since the permit was issued to Maymead in
December 2010.
Facility Contacts
The facility contacts are up to date in IBEAM. No one was on site to escort me for an inspection.
Facility Description
The facility is a hot mix asphalt batch plant rated at 100 tons per hour maximum capacity.
2. Compliance with specific permit conditions and limitations
Compliance with the permit conditions will be verified if the plant begins operating(visible emissions,I&M logs,
production,fuel,etc.).The facility stated in a July 2010 letter that the plant will not operate in the foreseeable future
(ref: recent telephone discussion with Mr. Sean Mackey). Specific Condition 10 of the permit requires a
notification within 15 days of the start-up and Specific Condition 8 requires Methods 5 and 202 stack testing within
60 days of the start-up.
3. Compliance History Review
The facility was issued a Notice of Deficiency on February 10,2017 for a late annual report. There have been no
other documented violations by the facility in the past five years.
4. Stack Test Review
Specific Conditions 8 of the permit requires Methods 5 and 202 stack tests within 60 days of start-up to demonstrate
compliance with NSPS, Subpart I and 2D .0506. Based on the last tests conducted,the facility is expected to be
capable of passing the required stack tests. The results of the September 2005 stack test are shown below.
