DEFINITIONS
DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot.
ND - Not Detected at or above adjusted reporting limit.
TNTC - Too Numerous To Count
J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit.
MDL-Adjusted Method Detection Limit.
PQL - Practical Quantitation Limit.

RL - Reporting Limit - The lowest concentration value that meets project requirements for quantitative data with known precision and
bias for a specific analyte in a specific matrix.
S - Surrogate
1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method 8270. The result for each analyte is
a combined concentration.
Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values.
LCS(D) - Laboratory Control Sample (Duplicate)
MS(D) - Matrix Spike (Duplicate)
DUP - Sample Duplicate
RPD - Relative Percent Difference
NC - Not Calculable.
SG - Silica Gel - Clean -Up
U - Indicates the compound was analyzed for, but not detected.
Acid preservation may not be appropriate for 2 Chloroethylvinyl ether.
A separate vial preserved to a pH of 4-5 is recommended in SW846 Chapter 4 for the analysis ofAcrolein and Acrylonitrile by EPA
Method 8260.

Permit No.: N/C/G/0/3/0/0/0/0/ or Certificate of Coverage No.: N/C/G/0/3/0/2/6/5/
Facility Name: Dave Steel Company, Inc.
County: Buncombe Phone No. 828-252-2771
Inspector: Reggie Reeves
Date of Inspection: 0510312021
Time of Inspection: 1150
Total Event Precipitation (inches): 0.56
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.

5. Floating Solids: Choose the number which best describes the amount of floating solids in
the stormwater discharge, where 1 is no solids and 5 is the surface covered with floating solids:
lO 2 3 4 5
6. Suspended Solids: Choose the number which best describes the amount of suspended
solids in the stormwater discharge, where 1 is no solids and 5 is extremely muddy:
1 0
3 4 5
7. Is there any foam in the stormwater discharge? Yes G
8. Is there an oil sheen in the stormwater discharge? Yes G
9. Is there evidence of erosion or deposition at the outfall? Yes No
10. Other Obvious Indicators of Stormwater Pollution:
List and describe: No indicators of stormwater pollution.
Note: Low clarity, high solids, and/or the presence of foam, oil sheen, or erosion/deposition
may be indicative of pollutant exposure. These conditions warrant further investigation.
