General Business: 6.2

Title: Consideration and possible authorization to allow the Treatment Plant Manager to enter into an Industrial Waste and Disposal Agreement with Waste Management, in the amount of $35,000, to dispose of impacted and solid waste material encountered during excavation activities on the Regional Transportation Commission Southeast Connector, Phase I Project.

Petitioner/Presenter: Neil C. Krutz P.E., Deputy City Manager/Michael Drinkwater P.E., Plant Manager

Recommendation: Staff recommends City Council authorize the Treatment Plant Manager to enter into an Industrial Waste and Disposal Agreement with Waste Management, in the amount of $35,000 per Exhibit A attached.

Financial Impact: There is no General Fund impact. The City of Sparks will manage the excavation and disposal of the impacted and solid waste material project using existing TMWRF Operating Budget. Sparks staff will enter into a services agreement with Waste Management to accept the estimated amount of 2,900 cubic yards of contaminated soil to the Lockwood Landfill at an estimated cost of $35,000.00; broken down as $11.00 per cubic yard plus incidental fuel charges per Exhibit A attached. This expense will be charged to TMWRF, Fund 5605, Account 603507, Site Improvements-Non Cap, under Program 131500, TMWRF Administrations, sub program of 101, Soil Remediation. Following quarterly reconciliation of TMWRF’s operating expenses, affecting the Sanitary Sewer Operations fund (1630), Sparks is expecting reimbursement from the City of Reno based on actual flow splits provided by ADS Environmental as outlined in the interlocal agreement for the operations of the facility, for the actual cost of this contract. The flow split for fiscal year ending June 30, 2013, was 32.39% / 67.61% for the Cities of Sparks and Reno respectively and the approximate split is outlined in Table 1 (attached).

Total Costs: $35,000.00

Fund: Joint Treatment Plant Account: 603507
Program: TMWRF Administration (131500)
Amount: $35,000.00 Budget Status: Budget Exists

A Business Impact Statement is not required because this is not a rule.

Agenda Item Brief: To minimize disposal cost of the impacted and solid waste material encountered during excavation activities on the Regional Transportation Commission Southeast Connector, Phase I Project, the City of Sparks will enter into an industrial waste and disposal services agreement with Waste Management.

Background: The Washoe County Health Department and Waste Management have granted approval to dispose of the impacted and solid waste material at the Lockwood landfill.

Analysis: On March 27, 2013 Kiewit encountered solid waste (trash, metal wood, and miscellaneous solid waste) and impacted soil during excavation activities associated to Retention Basin #1 on the Regional Transportation Commission (RTC) Southeast Connector, Phase I Project. The property where the solid waste and impacted material was discovered is jointly owned by the City of Sparks and City of Reno. Approximately 6,000 cubic yards of the solid waste material was excavated of which approximately 1,700 cubic yards was stockpiled onsite with the remaining material being transported to an offsite material storage facility secured by the RTC. CH2MHill, a RTC consultant, collected several composite soil samples from the excavated material for analytical testing. Hydrocarbon range organics (TPH-diesel and TPH-oil) were reported in the soil samples. Two release reports associated with the impacted material are on file with NDEP. The first release/spill report (NDEP Spill Report #130409-01) was associated with the trash/solid waste. The second release/spill report (NDEP Spill Report #130503-01) was associated with the impacted soil. In May 2013, the City of Sparks retained McGinley and Associates (MGA) to provide consulting services associated with the on-site impacted material. In June 2013, MGA conducted a Phase II Environmental Site Assessment (ESA) in the impacted area. The investigation included excavating 28 exploratory test pits and collecting soil and groundwater samples. MGA also conducted a limited Phase I ESA to identify potential source(s) of the impacted material. The results of the ESA activities were presented in the report entitled “Results of Environmental Site Assessment Activities and Work Plan for Soil Remediation, October 2, 2013”. The findings of the Phase I ESA could not truly identify the specific source(s) of the solid waste and impacted soil. Steamboat Creek originally traversed through the area where the solid waste and impacted soil were discovered. The creek was re-configured to its current configuration in the 1960’s by the U.S. Army Corp of Engineers. Much of the impacted material is located in the area where a former “ox-bow” was located. One theory is that the ox-bow became a waste disposal area (un-permitted landfill) when it dried up following the reconfiguration of Steamboat Creek. The Washoe County Health Department and Waste Management have granted approval to dispose of the impacted and solid waste material at the Lockwood landfill. RTC has assumed responsibility for the disposal of the material that was transported offsite. To minimize disposal cost of the impacted and solid waste material encountered during excavation activities on the Regional Transportation Commission Southeast Connector, Phase I Project, the City of Sparks will enter into an industrial waste and disposal services agreement with Waste Management.

Alternatives: 1.The Council could authorize the Treatment Plant Manager to enter into an Industrial Waste and Disposal Agreement with Waste Management, in the amount of $35,000 as outlined by staff. 2.The Council could reject the authorization and provide direction to the City Manager

Recommended Motion: “I move to authorize Treatment Plant Manager to enter into an Industrial Waste and Disposal Agreement with Waste Management, in the amount of $35,000, to dispose of impacted and solid waste material encountered during excavation activities on the Regional Transportation Commission Southeast Connector, Phase I Project.”
