The possible causes could be that a heavy down pour washed sediment, dust, and dirt from the tires of
heavy trucks, into that outfall. We keep that area clean and swept as much as possible.
The outfall contains a significant amount of sediment. WCP will look into hiring a contractor to properly
clean drainage area.
If you have any questions please feel free to call me at [phone].
Sincerely,
Tony R. Sprinkle
Environmental & Facilities Supervisor

Stormwater Discharge Calculations
WIELAND COPPER PRODUCTS, LLC
2020 Calendar Year
Rationale for Discha ge Calculations
The rational formula is used for the basis of the calculations. The rational formula has been
developed to calculate the rate of run-off from a rain event of a given intensity over a given area.
The formula is written:
Q=CIA
where: Q is the rate of run-off flow in cubic feet per second (CFS)
I is the rain intensity in inches per hour
A is the land area contributing run-off to the discharge point
and: C is a run-off coefficient which ranges from 0 for a completely pervious surface to
1.0 for a completely impervious surface.
The rational formula results from the fact that, for a completely impervious surface, a rainfall of
one inch over a period of one hour on an area of one acre will result in a run-off discharge of one
CFS. The run-off coefficient C can be thought of as a correction factor based on the percentage
of the total rainfall which will run off from a given area due to how pervious or impervious the
surface of that area is. Since the discharge permit for this facility requires an estimate of the total
discharge from the storm event during which samples are collected, we will use a modified form
of the rational formula to calculate the total discharge as follows:
Qt = CRA (0.027)
where: Qt is the total discharge in Million Gallons
C is the run-off coefficient as defined above
R is the total amount of rainfall in inches
A is the surface area contributing flow to the sample location in acres
and: The constant 0.027 in the modified equation corrects the units to Million Gallons
(MG) based on the fact that 1 acre -inch = 0.027 MG
For drainage areas which are comprised of a combination of pervious and impervious areas, the
formula can be written as follows:
Qt = [CiAI + C2A21 (R) (0.027)
where: C1 = C factor for pervious areas
Al = pervious area contributing to the outfall in acres
C2 = C factor for impervious areas
A2 = impervious area contributing to the outfall in acres

Discharge Calculations
The total rainfall for the August 21, 2020 storm during which samples were collected at this facility
was 1.43 inches. We will use generally accepted conservative estimates of the run-off coefficient of
C=1.71 for impervious areas, and C= 0.50 for pervious areas.
The drainage areas contributing to each of the five outfalls as follows:
Outfall
Total Area (acres)
Pervious Area (acres)
@ C=0.50
Impervious Area
(acres) @ C=0.90

Total Discharge at Stormwater Discharge Outfall 001
Qt = [(0.50)(18) + (0.90)(12)] (1.43) (0.027)
Qt = 0.764 MG
Total Discharge at Stormwater Discharge Outfall 002
Qt = [(0.50)(2.63) + (0.90)(2.63)] (1.43) (0.027)
Qt = 0.142 MG
Total Discharge at Stormwater Discharge Outfall 003
Qt = [(0.50)(8.05) + (0.90)(3.45)] (1.43) (0.027)
Qt = 0.275 MG
Total Discharge at Stormwater Discharge Outfall 004
Qt = [(0.50)(6.2) + (0.90)(9.3)] (1.43) (0.027)
Qt = 0.443 MG
Total Discharge at Stormwater Discharge Outfall 005
Qt = [(0.50)(25.7)(1.43) (0.027)]
Qt = 0.496 MG

All permits require qualitative monitoring to be performed during a "measurable storm event."
A "measurable storm event" is a storm event that results in an actual discharge from the permitted site
outfall. The previous measurable storm event must have been at least 72 hours prior. The 72-hour storm
interval does not apply if the permittee is able to document that a shorter interval is representative for
local storm events during the sampling period, and the permittee obtains approval from the local DEMLR
Regional Office.
