In NOI section 3 ldquoContaminant Informationrdquo when the number of samples was noted with an asterisk only the most recent water sampling date was utilized Concentrations of Total Metals and Elevated TSS were identified as part of the pre-characterization of groundwater An additional sample was collected after groundwater was allowed to settle in a container to evaluate the effects this would have on total metals concentrations and TSS As anticipated the concentrations decreased Based on this information the proposed means to manage groundwater effluent through sedimentation basin and hay balesilt fence filtration should provide sufficient reduction in concentrations prior to the receiving water body Effluent sampling will occur in accordance with the NPDES permit requirements to monitor for the compounds identified during pre-characterization

Laboratory analytical data packages for the sampling are attached to this NOI

DATA COMMENT PAGE

Organic Data Qualifiers

ND Indicates compound was analyzed for but not detected at or above the reporting limit

J Indicates an estimated value This flag is used either when estimating a concentration for tentatively identified compounds where a 11 response is assumed or when the data indicates the presence of a compound that meets the identification criteria but the result is less than the sample quantitation limit but greater than the method detection limit

H Method prescribed holding time exceeded

E This flag identifies compounds whose concentrations exceed the calibration range of the instrument for that specific analysis

B This flag is used when the analyte is found in the associated blank as well as in the sample

R RPD outside accepted recovery limits

RL Reporting limit defined as the lowest concentration the laboratory can accurately quantitate

S Spike Recovery outside accepted recovery limits

See Case Narrative

Micro Data Qualifiers

TNTC Too numerous to count

Inorganic Data Qualifiers

ND or U Indicates element was analyzed for but not detected at or above the reporting limit

J Indicates a value greater than or equal to the method detection limit but less than the quantitation limit

H Indicates analytical holding time exceedance

B Indicates that the analyte is found in the associated blank as well as in the sample

MSA Indicates value determined by the Method of Standard Addition

+ Indicates the correlation coefficient for the Method of Standard Addition is less than 0995

E This flag identifies compounds whose concentrations exceed the calibration range of the instrument for that specific analysis

R RPD outside accepted recovery limits

RL Reporting limit defined as the lowest concentration the laboratory can accurately quantitate

S Spike Recovery outside accepted recovery limits

PS The analyte was below the Reporting Limit but has significant matrix interference as noted by the poor recovery of the Post Digestion Spike

See Case Narrative

MCL Exceeded

Report Comments 1 Soil sediment and sludge sample results are reported on a dry weight basis 2 Reporting limits are adjusted for sample size used dilutions and moisture content if applicable

DATA COMMENT PAGE

Organic Data Qualifiers

ND Indicates compound was analyzed for but not detected at or above the reporting limit

J Indicates an estimated value This flag is used either when estimating a concentration for tentatively identified compounds where a 11 response is assumed or when the data indicates the presence of a compound that meets the identification criteria but the result is less than the sample quantitation limit but greater than the method detection limit

H Method prescribed holding time exceeded

E This flag identifies compounds whose concentrations exceed the calibration range of the instrument for that specific analysis

B This flag is used when the analyte is found in the associated blank as well as in the sample

R RPD outside accepted recovery limits

RL Reporting limit defined as the lowest concentration the laboratory can accurately quantitate

S Spike Recovery outside accepted recovery limits

See Case Narrative

Micro Data Qualifiers

TNTC Too numerous to count

Inorganic Data Qualifiers

ND or U Indicates element was analyzed for but not detected at or above the reporting limit

J Indicates a value greater than or equal to the method detection limit but less than the quantitation limit

H Indicates analytical holding time exceedance

B Indicates that the analyte is found in the associated blank as well as in the sample

MSA Indicates value determined by the Method of Standard Addition

+ Indicates the correlation coefficient for the Method of Standard Addition is less than 0995

E This flag identifies compounds whose concentrations exceed the calibration range of the instrument for that specific analysis

R RPD outside accepted recovery limits

RL Reporting limit defined as the lowest concentration the laboratory can accurately quantitate

S Spike Recovery outside accepted recovery limits

PS The analyte was below the Reporting Limit but has significant matrix interference as noted by the poor recovery of the Post Digestion Spike

See Case Narrative

MCL Exceeded

Report Comments 1 Soil sediment and sludge sample results are reported on a dry weight basis 2 Reporting limits are adjusted for sample size used dilutions and moisture content if applicable
