DocuSign Envelope ID: 18C4E672-1 DB7-4020-9D85-083D0D588F92 Exhibit A: Project Specifications for Sewer Line Cleaning and Video Recording Overview It is the intent of these specifications to provide enough information for a Contractor with the proper equipment to clean the gravity sewer lines and produce a video (DVD) after cleaning that shows the condition of the inside of the lines. For this project, Orange County will supply the following: • A map of the lines to be cleared — Exhibit B • A water source, likely a hydrant on the Orange Alamance Water System (OAWS) in the vicinity of the lines to be cleaned. • Coordination with and by our sewer maintenance entity, the City of Mebane, to control pump station operations such that they do not interfere with your sewer cleaning operation. • Coordination with the City of Mebane to allow the disposal of waste from the cleaning process at the City of Mebane Wastewater Treatment Plant at no charge. • Notification to all the Efland Sewer customers that line cleaning and video recording will be taking place. The Contractor will be expected to provide all equipment and labor to clean and video the specified gravity sewer lines of the sewer system, as described more completely below. The selected Contractor will be responsible for maintaining a safe working environment and adhering to all confined space and/or sewer work requirements. SCOPE OF WORK Cleaning This project consists of cleaning and videoing (CCTV) 8" gravity sewer lines. The project is divided into three (3) phases as followings: • Phase 3 — approximately 7,300 linear feet • Phase 4 — approximately 5,600 linear feet • Phase 5 — approximately 5,900 linear feet Some of the lines to be cleaned are off-road, in cross-country easements. These easements will be cleared prior to cleaning and will be passable, i.e. stumps will be cut to ground level and overhanging limbs will be removed, but there is no "road" along the easement. Contractors interested in bidding the project are encouraged to investigate the project area beforehand and bid accordingly. Water for cleaning will be supplied by Orange County, most likely from a nearby hydrant. The hydrant does not belong to Orange County, but rather to the Orange-Alamance Water System (OAWS). There will be no charge to the contractor for the water used, but the contractor will need to coordinate with OAWS to get a water meter installed on the hydrant they will use and record the amount of water used and will need to coordinate the withdrawal of water with OAWS directly. Sewer line cleaning shall be performed to remove foreign material from the sanitary sewer lines for clear viewing of the interior surface of the pipe during the video inspection and restore the pipe to at least 95% original capacity. Conditions discovered in the pipe, such as protruding pipes, blockages, roots, etc. that can be removed by conventional means, e.g. cutting, should be removed by the Contractor as part of the performance of
