1".We request that remaining well pairs have their vertical gradient magnitudes and direction(s) determined in order to achieve compliance with MRP R1-2010-0023. This item remains a violation until the required analyses are provided."
2."Hence, the lack of DO (dissolved oxygen) measurement during the first monitoring effort under MRP R1-2010-0023 remains a violation of the order. We will not be issuing a fiscal penalty for this violation..."
3."We were unable to determine that the SHN Water Sampling Data Sheet ...actually contains three well casing volumes." "Hence this item is removed."
4."Thank you for indicating that Total Petroleum Hydrocarbons (THP) as Motor Oil (TPHMO) from MW-20 will be presented in tabular form. This item is resolved."
5."We rechecked Table 2 (MW-1) footnotes which indicate organic compounds exist that elute out on the TPH as gasoline range and in the diesel range, albeit at low concentrations". "This item still needs to be resolved."
6."Thank you for implementing field filtering and only analyzing for specific constituents of concern (i.e. dissolved hexavalent chromium..."
This item is resolved...
7."We request that monitoring and analyses be implemented as per MRP R1-2010-0023. This item appears to be resolved but results from the next sampline and reporting effort will confirm or reject resolution of this item."
8. "We appreciate the correlations that SHN has developed between total dissolved solids (TDS) and specific conductance (SC)....This item appears to be resolved."
9."...the Document does not adequately describe what corrective actions would be applied for either field or laboratory events..." "We request that corrective action discussion be expanded so that we are not guessing what would happen when correctivwe actions are needed...This violation is not yet resolved."
10."Based on the locations of MW-12 and MW-20, a threatened discharge to Humboldt Bay exists and therefore preparation of an interim remedial action (IRA) is appropriate to prevent and minimize the threatened discharge to Humboldt Bay."
11."This item is not resolved and further data collection is required."
12. "These maps will be prepared as part of the Site conceptual model to be submitted in December 2010."
"On August 23, 2010, we received notification from SHN that AOI-8 field work will begin on September 13, 2010, with estimated 5-day duration....This email also indicates that the second half 2010 groundwater mo9nitoring effort would occur the week of September 13, 2010."
