598-2022

The City of Portland ordains:

Section 1. The Council finds:

1. The Bureau of Environmental Services has ten digesters at the Columbia Blvd. Wastewater Treatment Plant.  To maintain their efficiency, they need to be periodically cleaned.  This translates into cleaning five (5) digesters per year per contract with Synagro
2. Clean digesters increase the organic material capacity therefore augmenting the potential of biogas production. By having clean digesters that contain mostly organic material, this increases the efficiency of the plant by maximizing digester volume for regulatorily mandated detention time and volatile solids reduction, increase bio-gas production as well as reducing the potential of sending flows to the plant's facultative lagoon when the digesters have reached their capacity.
3. On February 19, 2020, City Council approved Ordinance No. 189865 authorizing a competitive solicitation for digester cleaning services and the resulting contract No. 30007677 for an estimated annual cost of $1, 250,000, for a total not-to-exceed cost of $6,250,000 over five (5) years.
4. An error occurred in the original establishment of Contract 30007677; the pricing provided by Synagro estimated the annual cost for cleaning five digesters to be $1,776,335.25 but this was not reflected on page one of the Contract which established the annual amount to be $1,250,000.00, therefore the annual amount needs to be increased by $526,335.25.
5. Another error to the original contract occurred on page 37, Section 4, Project Schedule, 4.1; Number of Digesters should read 5 per year instead of 3 to coincide with the intent of this Contract on its inception.
6. Metro has introduced an excise tax, which increases the operating costs of Vendors performing this work. As such, Synagro has absorbed the costs for the first year, but will need a price change to account for the new tax beginning July 1, 2022. The price increase requested by Synagro is a 2.8% increase to the cost per dry ton of waste hauled, from $594.50 to $611.15 for an additional $50,317.25 per year for four years.
7. The requested amendment increases the annual cost from $1,250,000 to $1,826,652.50 for a not-to-exceed total value of $9,082,945.25.  Funds are available in the Sewer System Operating Fund, FY 2022-23 Budget, Bureau of Environmental Services,  ESOM000003

NOW, THEREFORE, the Council directs:

1. The Chief Procurement Officer is authorized to execute an amendment to Contract No. 30007677 with Synagro for the purposes described in Section 1, in a form similar to the amendment added as Exhibit A, to increase the not-to-exceed contract value to $9,082,945.25, provided the amendment has been approved as to form by the City Attorney’s Office.
2. The Mayor and Auditor are hereby authorized to draw and deliver warrants chargeable to the Sewer System Operating Fund Budget when demand is presented and approved by the proper authority.
