WORTH, TX EXHIBIT A - SCOPE 1) Costs associated with the activities listed below are detailed in Exhibit B. 2) Commencement Date: April 51}i, 2025 at 12:00 am. 3) Biosolids Dewatering Activities. a. Existing belt press facility. Starting on the Commencement Date Renda shall have personnel onsite to verify the working condition of the existing assets in the belt press building, as well as the sludge levels in the three storage tanks. Based on information gathered that morning, and with prior written approval from the City, Renda will commence with dewatering activities utilizing the assets in the existing belt press facility. i. Renda will utilize lime for feedstock processing only upon written approval by the City. See Section 14(b) below. ii. Processing of incoming sludge (feedstock) from the Village Creek Water Reclamation Facility (VCWRF) shall be done in accordance with Section 4 below. b. Renda shall construct and utilize a temporary belt -filter press line for the purposes of processing dredged materials from the onsite storage ponds. If needed, the temporary belt press line shall also have the ability to process incoming feedstock from the VCWRF, however this shall be done in accordance with Section 4 below. i. The temporary belt press line shall include the dewatering equipment and asphalt storage pad as described in Exhibit B ii. Renda will utilize lime for dredged materials only upon written approval by the City. See Section 14(b) below. iii. Renda will provide, at no extra cost, any temporary hoses, pipelines, or pumps to process dredged materials or feedstock via the temporary belt press line. c. Renda will be responsible for supplying all polymer and lime for processing materials via the temporary belt press line and the existing Belt Press Facility. d. Operate valves and mixers associated with the three onsite storage tanks. These activities will be done in coordination with City, specifically for those times when the feedstock is to be diverted to dryer facility operations. See Section 4 below. The City will assume full responsibility for tank mixing activities upon issuance of written notification to Renda. e. As needed and appropriate, coordinate with the City on ferric chloride dosing activities. The City will be responsible for setting chemical dosing rates, and will also pay the cost for the ferric chloride. £ Operate the return flow pump station to return the filtrate, centrate, process water and stormwater back to the VCWRF. Provide any temporary pumping solutions, such as portable diesel pumps, to ensure wastewater is pumped back to VCWRF. Utilize best management practices to reduce the solids loading retuned back to VCWRF. The City will assume full responsibility for return flow pumping activities upon issuance of written notification to Renda. g. Renda will provide, at no extra cost to the City, fuel for its vehicles and other assigned operations (such as portable diesel pumps). This includes trucking operations. h. Renda will assume responsibility for retaining the services of a qualified third party contractor to perform routine calibrations of the onsite truck scales (frequency once per two months). The City will assume full responsibility for truck scale calibration upon issuance of written notification to Renda. 4) Feedstock Processing. a. In regards to the VCWRF feedstock, the City will prioritize the production of the dried Class A pelletized product, or alternatively the production of centrifuged cake (again from the VCWRF feedstock). During these times, the processing of feedstock via belt filter presses may not be needed. Upon written notice from the City, Renda will either reduce or halt belt pressing operations of the feedstock so that the City can utilize the rotary drum dryer / centrifuges. Similarly, upon written notice from the City, Renda will utilize belt presses to provide dewatering of feedstock as needed. b. Odor Control Best Management Practices at the Biosolids Dewatering Facility. Due to recent odor impacts on the surrounding community, it is imperative that steps be implemented to reduce the potential for offsite odors. This includes minimizing the quantities of stockpiled materials (weather permitting), minimizing hold times prior to hauling materials offsite, as well as other potential odor control measures. The City will work with Renda to identify and implement needed odor control measures, and may consider a contract amendment to implement any mutually agreeable solution(s). 5) Pond Dredging Operations a. Perform molybdenum sampling of the north pond based on the previous sampling protocols established by Jacobs Engineering. Coordinate with the City to evaluate molybdenum sample results. Any material found to be above TPDES or other regulatory limits will sent off for appropriate disposal (such as landfilling). b. The City's priority is to landfill all dredged materials. However, if landfill capacity is limited or unavailable, then the City will issue a written notification for Renda to process the dredged materials to meet Class AB standards. Please note this does not include the materials described in Section 5(a) or 5(e) of this Exhibit. c. For material processed to Class AB standards, Renda will handle and load these materials onto trucks and transport them offsite for beneficial reuse. These activities will be performed in accordance with Section 15 below. d. If needed, and upon written concurrence from the City, dredged materials may be processed to Class AB standards utilizing the method described in Section I l(c) of this Exhibit. e. Dredged materials from the south pond will be landfilled. f. Odor Control Best Management Practices at the Biosolids Dewatering Facility. Due to recent odor impacts on the surrounding community, it is imperative that steps be implemented to reduce the potential for offsite odors. This includes minimizing the quantities of stockpiled materials (weather permitting), minimizing hold times prior to hauling materials offsite, as well as other potential odor control measures. The City will work with Renda to identify and implement needed odor control measures, and may consider a contract amendment to implement any mutually agreeable solution(s). 6) Condition Assessment a. Perform a detailed condition assessment of the assets within the existing Belt Press Building, as well as the mixers on the sludge storage tanks and the return flow pump station. Compile a report detailing the findings of the condition assessment, with recommendations on needed repairs, equipment replacements, or potential upgrades. Provide a detailed line item cost estimate for performing such work. 7) Maintain and repair functional equipment associated with the Belt Press Building, storage tanks, chemical feed station, and return flow pump station. Equipment that is turned over to Renda in poor or inoperable conditions may be repaired, replaced or upgraded as detailed in Section 6 above. 8) 5 MG Storage Tank Cleaning. Upon conferring with the City, begin tank cleaning operations as soon as practicable. Removed materials will be sent to a landfill for disposal. 9) Pre -Existing Stockpiled Materials. a. The City's priority is to landfill materials that were stockpiled prior to the Commencement Date. All landfill tipping fees will be a pass -through cost to the City. Renda will coordinate with area landfills for the purpose of disposing of these materials. b. If landfill capacity is limited or unavailable, then the City may issue a written request for Renda to reprocess the pre-existing stockpiled materials to meet Class AB standards. Renda will then load these materials onto trucks and haul them offsite for beneficial reuse, but again only after receiving written notice from the City. These activities will be done in accordance with Section 15 below. c. If needed, and upon written concurrence from the City, pre-existing stockpiled materials may be processed to Class AB standards utilizing the method described in Section I I (c) of this Exhibit. 10) Class A Biosolids a. The City is responsible for ensuring the dried pelletized product meets all Class A standards, including those for pathogens and vector attraction reduction. b.
