Circor Pumps North America, LLC — Monroe, North Carolina
Certificate of Coverage NCGO30293
Dear Mr. Khan:
On behalf of Circor Pumps North America, LLC (Circor) — Monroe facility, Shield
Engineering, Inc. (Shield) is submitting a revision to the Tier Three Action from Third
Quarter 2021, for the Tier Three exceedance of Copper. This Action Plan is attached, for
your reference.
According to the Third Quarter 2021 Action Plan, Circor's selected actions were to engage
a contractor to sweep the site and to implement routine sweeping of the site. Circor
contacted and engaged a contractor for this purpose and sweeping of the site took place
in 41h Quarter 2021. Since that time Circor has applied increased general housekeeping
practices in the areas of concern and as a result of these efforts, the site has had two
consecutive sampling events at or below the benchmark for Copper, as shown below:
Copper (benchmark = 0.010 mg/1)

INTRODUCTION
This Action Plan has been prepared in accordance with Part E-7(b) of General Permit for
benchmark exceedances which have triggered Tier Three Response. Tier Three status for
Copper at Outfall 004 has carried over from the previous General Permit. CIRCOR has made
progress towards addressing benchmark exceedances at Outfall 004 as evidence by the Zinc
concentrations during the previous permit term. Zinc exited Tier 3 at Outfall 004 during the
previous permit monitoring as there were only 2 exceedances of Zinc during that permit term. This
Action addresses Copper Tier Three Response.
ACTION PLAN ELEMENTS
The General Permit, Part E-7(b), requires specific elements be addressed. Each of these
elements are being addressed as follows:
f. Documentation of the Four Benchmark Exceedances
The table below documents the last 4 benchmark exceedances for Copper at Outfall 004 for
CIRCOR.

H. An Inspection report that covers the industrial activities within the drainage area of the
outfall with the exceedances (including the date of the inspection and the personnel
conducting the inspection)
See attached inspection report. The inspection covered all areas of industrial activity in the
drainage areas that drain Outfall 004 as well as Outfall 005. Roof stacks and vents associated
with potential airborne sources of pollutants (welding, painting, forklift recharging, blast room,
container and waste storage) are all located near the rear walls or east walls, thus associated
with Outfall 004.
The inspection report notes areas of concern observed as having the potential to contribute to
benchmark exceedances. A site map is attached for reference of the drainage area.
