PREVIOUS RELATED ACTION:
On March 16, 2020, City Council adopted a resolution to create CIP Project “Underground Storage Tanks – Work and Removal Plans,” Project No. 428-2590-XXXXX-71061, and appropriated $50,000 of General Funds to the Project.
On March 22, 2021, City Council appropriated an additional $50,000 of General Funds to the Project.
On March 7, 2022, City Council appropriated an additional $50,000 of General Funds to the Project.
On May 2, 2022, City Council approved Amendment No. 1 with Pinnacle Environmental Technologies in the amount of $18,054 (for a total of $72,879) for professional services to abandon and install new monitoring wells.
DISCUSSION:
In 2019, the LARWQCB met with City Staff to discuss mandatory corrective actions for existing underground storage tanks at four identified locations. The City of Pomona (City) is directed to take corrective action to ensure the protection of human health, safety, and the environment (pursuant to Health and Safety Code Section 25296.10). Any person who violates any corrective action requirement established by, or issued pursuant to, Health and Safety Code Section 25296.10 is liable for civil penalty of not more than ten thousand dollars ($10,000) for each underground storage tank for each day of violation.
In 2020, the Project was created (Attachment No. 2) in response to the LARWQCB requirement to prepare and submit technical work plans. The City worked with Pinnacle Environmental Technologies (Pinnacle) to submit work plans and testing data to the LARWQCB for all four sites.
In 2022, based on the submitted work plans, the LARWQCB recommended the closure of cases (Case R-12421; Case R-66210) at two of the four identified sites; required six new groundwater monitoring wells at the Brackett Field Pomona Police Heliport (Case No. R-02777); and notified the City of pre-closure at Fire Station No. 182 (SCP No. 1577). Pinnacle was the lowest responsive bidder selected to install the new monitoring wells and submitted all testing results based on LARWQCB-approved work plans.
In January 2023, the LARWQCB sent the City a letter requiring additional subsurface environmental assessment for Fire Station No. 182 (SCP No. 1577).
In February 2023, the LARWQCB sent the City a letter denying the City’s request to close the case at the Brackett Field Pomona Police Heliport (Case No. R-02777) and required one additional monitoring well to verify the extent of the soil contamination. Pinnacle provided cost proposals to address the items listed in LARWQCB letters for both sites. Due to additional work required by LARWQCB, the amendment for this Project exceeds 25% and requires City Council approval to proceed.
