Hello Ray,

Attached you will find the IRAM Work Plan Addendum No. 8 for a seventh injection of bioremediation amendments at the PCC Structurals SSBO facility (ECSI #1617). We are scheduled to begin the injection event mid-August and would appreciate an expedited DEQ review. Please let us know if you would like to discuss.

Have a great weekend. Thank you,

// ERIN WAIBEL RG
