Title: Consideration and possible approval of an additional environmental consulting services contract with McGinley & Associates, in the amount of $27,225, to perform remediation coordination of the off-haul and backfill 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 award the additional environmental consulting services contract to McGinley & Associates, in the amount of $27,225.

Financial Impact: There is no General Fund impact. McKinley and Associates was engaged by The City of Sparks under Purchase Order No. 100008872, using TMWRF operating budget, to conduct an assessment and testing of the contaminated soil to ascertain the degree of remediation required. This additional environmental consulting services contract coordinates the actual remediation steps needed, also using TMWRF Operating Budget. Project Administration costs will be up to $27,225.00. This expense will be charged to TMWRF, Fund 5605, Account 603242, Professional Services- Other, 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 both the initial assessment work as well as this agreement. 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: $27,225.00

Fund: Joint Treatment Plant Account: 603242
Program: TMWRF Administration (131500)
Amount: $27,225.00 Budget Status: Budget Exists

Business Impact (Per NRS 237):
A Business Impact Statement is not required because this is not a rule.

Agenda Item Brief: McGinley and Associates will provide consulting services to oversee the remediation of the impacted soil and solid waste that is currently stockpiled onsite (approximately 1,700 cubic yards) and the activities proposed in the remedial action plan (excavation/disposal of approximately 1,100 cubic yards of impacted soil/waste and import and placement of backfill material).

Background: In May 2013, the City of Sparks retained McGinley and Associates (MGA) to provide consulting services associated with the on-site impacted material. MGA is knowledgeable of all aspects of the impacted and solid waste material encountered. MGA will be responsible for: conducting additional site testing as required, attend coordination meetings with regulatory agencies, prepare a corrective action plan and waste disposal document, oversee excavation, backfill and haul off operations, and prepare a final report for submittal to Washoe County Health Department.

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.

Alternatives: 1. The Council could approve the additional environmental consulting services contract as outlined by staff 2. The Council could reject the contract and provide direction to the City Manager

Recommended Motion: “I move to approve the additional environmental consulting services contract with McGinley & Associates, in the amount of $27,225, to perform remediation coordination of the off-haul and backfill of impacted and solid waste material encountered during excavation activities on the Regional Transportation Commission Southeast Connector, Phase I Project.”
