As per EPA’s e-mail of April 20, TRC will resample these locations 

previously sampled by GCC. We are resampling them as the detection limits 

for the samples were too high to make a conclusive decision on BAP 

exceedence. Since Zinc was below the soil SRG at these locations, analysis 

will be limited to semi volatiles that constitute the BAP Equivalent 

parameter. 

 

SB 44 : GCC sample depth was 1 to 1.5 feet. The 2 to 2.5 depth sample at 

this location was below SRG. TRC will sample the soil in this area between 

depth of 1 to 1.5 feet or immediately below asphalt if asphalt depth is 

greater than this depth. 

 

SB 45.: GCC sample depth was 1 to 1.5 feet. The next sample taken at 4 to 

4.5 feet was below SRG. TRC’s sampling plan is same as SB44. 

 

SB47: GCC sample depth was 0.0 to 0.5 feet. TRC will sample this depth 

unless it is an asphalt. In that case , we will sample at depth where we 

first encounter soil. 

 

SB47B: GCC sample depth was 1.5 to 2.0 feet. TRC will sample at this depth. 

 

SB48: GCC sample depth was 0.3 to 0.8 feet. The next sample at this 

location was at depth of 2.0 to 2.5 feet and it was below SRG. TRC will 

000481
sample at this depth or at depth at which we first encounter soil. 

 

SB54: GCC sample depth was 1.0 to 2.0 feet. TRC will sample at this depth 

as long as it is below the asphaltic material. 

 

If field observations led us to believe that samples being submitted for 

analysis seem contaminated based on visual or odor considerations, TRC 

will take a sample at a lower depth to determine the depth of clean soil 

zone. This will avoid the need to come back and resample. 

 

We are planning to obtain these samples on coming Thursday. 

 

I trust this meets our understanding. Let me know if you have questions or 

comments. We will be asking Pace labs to keep the detection limits as low 

as possible so we can have a conclusive determination on presence of BAP 

equivalents.

David/Riaz, I am sending this email to summarize the conversation between 

Riaz and myself this morning. 

1. We have agreed to call all of the NAPL located within the aquifer 

000483
units 'DNAPL'. An explanation of the occurrence of the DNAPL within the 

upper intermediate aquifer will support this notation. 

2. The remedial action reports will be revised based on information 

obtained from the lower and upper DNAPL investigations. Because of this, 

the revisions will be submitted following completion of the upper 

intermediate investigation. 

3. The map depicting the GCC samples vs. the soil excavation areas has 

been reviewed. There are five points that do not fall within the 

boundaries of the excavated areas. All of which have questionable high 

detection limits. All but two were taken at a depth of 1.0 feet below 

ground surface or greater. The two at shallow depths have lower detection 

limits, but when used to calculate the BAP equivalent, result in an 

exceedance of 7.8 mg/kg. It was agreed that confirmation samples would be 

taken in these areas to confirm the presence of COCs. Based on the 

results of these samples, a decision can be made regarding action. 

SB-44 (200,000 ug/kg) 

SB-45 (34,000 ug/kg) 

SB-54 (35,200 ug/kg) 

SB-47B 1.5 to 2.0 (3550 ug/kg) 

SB-47 0 to 6in (3450 ug/kg) 

SB-48 3 to 8in (3430 ug/kg)
