Authorize agreement with Blue Sky Environmental for multiple hearth furnace source testingCentral Contra Costa Sanitary District e BOARD OF DIRECTORS POSITION PAPER Board Meeting Date: March 20, 2014 Subject: AUTHORIZE THE GENERAL MANAGER TO APPROVE THE TECHNICAL CONSULTING SERVICES AGREEMENT WITH BLUE SKY ENVIRONMENTAL, INC., FOR MULTIPLE HEARTH FURNACE SOURCE TESTING Submitted By. Initiating DeptJDiv.: Randy Schmidt, P.E. Operations Department / Regulatory Senior Engineer REVIEWED AND RECOMMENDED FOR BOARD ACTION: Curtis W. Swanson, Director of Operations , R. Bailey General Managel ISSUE: In accordance with the purchasing procedures, Board authorization is required for the General Manager to execute a Technical Consulting Services Agreement in an amount greater than $100,000. RECOMMENDATION: Authorize the General Manager to approve a Technical Consulting Services Agreement with Blue Sky Environmental, Inc., not to exceed $155,000 for multiple hearth furnace (MHF) source testing to comply with Title V Air Permit requirements and to determine compliance with the upcoming Sewage Sludge Incinerator regulations under Section 129 of the Clean Air Act (Section 129). FINANCIAL IMPACTS: The total anticipated cost for the source testing is $155,000. ALTERNATIVES /CONSIDERATIONS: The Board could reject the proposed contract. This is not recommended for two reasons. First, the Title V Air Permit requires a source test of MHF No. 2 every 60 months, and failure to do so will result in enforcement action from the Bay Area Air Quality Management District. Second, the source test data from MHF No. 2 is needed to demonstrate that the District can meet future standards for Sewage Sludge Incinerators under Section 129. BACKGROUND: The District is required to conduct an annual emission test on the operating MHF to demonstrate Title V compliance. Typically, any additional internal engineering evaluation studies are conducted at the same time to minimize labor and mobilization cost. In March 2013, the District conducted an emissions source test on MHF No. 1 and confirmed that MHF No. 1 can meet the emission limits under Section 129 at normal operating conditions. Section 129 emission limits for sewage sludge incinerators will be effective in March 2016. The proposed source test will evaluate the emissions data on MHF No. 2 while firing at two different conditions: natural gas and sludge, and landfill gas and sludge. The 2014 source test is scheduled to begin in early May and will last for approximately four calendar weeks.

AUTHORIZE THE GENERAL MANAGER TO APPROVE THE TECHNICAL CONSULTING SERVICES AGREEMENT WITH BLUE SKY ENVIRONMENTAL, INC., FOR MULTIPLE HEARTH FURNACE SOURCE TESTING Staff conducted a request for proposal process and selected Blue Sky Environmental, Inc., to conduct the 2014 testing of furnace air emissions. The proposed scope for the 2014 source test on MHF No. 2 will include: 1. Five -year Title V Testing This source test will demonstrate compliance with the Bay Air Quality Management District's five -year Title V source testing requirements. 2. Section 129 of the Clean Air Act Compliance Determination The results of this source test will serve as an engineering assessment of compliance with the Section 129 emission limits. The source test will include measurements of the following parameters: oxygen, carbon dioxide, carbon monoxide, nitrogen oxides, sulfur dioxide, total hydrocarbons, non - methane organic carbon, particulate matter (total, 2.5 microns and 10 microns), hydrogen chloride, dioxins /furans, mercury, cadmium, lead, beryllium, and trace metals. 3. Process Operating Limits for Title V and Section 129 of the Clean Air Act Compliance This source test will include testing at high and average sludge feed rate while firing on natural gas and landfill gas to demonstrate the District's ability to comply with the emission limits at multiple operating conditions and to establish reasonable operating limits for the MHF No. 2 temperature, wet scrubber pressure drop, pH, and flowrate. The high feed rate runs will be tested at 85 percent of the furnace's maximum permitted feed capacity and the average feed rate runs will be tested at approximately 70 percent of the maximum permitted feed capacity. The District's goal is to demonstrate the furnace's ability to meet Section 129 emission limits at various operating conditions and to establish site - specific pressure drop minimums with the Bay Area Air Quality Management District, which is the local regulatory authority for Section 129 compliance. 4. Landfill Gas Inlet Analysis Landfill gas samples will be collected on each day of emission testing. Samples will be analyzed for methane, oxygen, nitrogen, carbon dioxide, carbon monoxide, hydrogen sulfide, other hydrocarbons, and high heating value. RECOMMENDED BOARD ACTION: Authorize the General Manager to approve a Technical Consulting Services Agreement with Blue Sky Environmental, Inc., not to exceed $155,000 for MHF source testing to comply with Title V Air Permit requirements and to determine compliance with the upcoming Sewage Sludge Incinerator regulations under Section 129 of the Clean Air Act.
