Well Decommissioning Work Plan JACOBS 5. Sustainability Sustainability principles aimed at minimizing environmental impacts that PG&E and its contractors may have while implementing the proposed well decommissioning activities presented in this Work Plan are integrated into elements of the Work Plan. Applicable environmental stressors identified are as follows: • Greenhouse gas (GHG)emissions • Waste sent to landfills The potential for environmental impacts from GHG emissions and waste generation from this project will be minimized as described below. These well decommissioning activities should also positively affect occupational health and safety. By practicing sustainability in these areas, PG&E and its contractors will meet the present well decommissioning needs without compromising the environment. 5.1 Greenhouse Gas Emissions GHG emissions contribute to climate change. Most of the GHG emissions anticipated from this project will come from vehicle emissions. The following GHG reduction strategies will be considered when executing this Work Plan: • Combine field visits with office commutes to reduce automobile GHG emissions. • For personnel not based in the project area, stay in local lodging as much as practical to avoid additional GHG emissions created by long-distance commuting. • When feasible, use alternative energy or hybrid vehicles. • Avoid idling vehicles when not in use. • Follow preventative maintenance schedules to optimize vehicle performance. It is assumed that an estimated 10 percent savings in GHG emissions can be achieved resulting from proactive preventative maintenance. • When possible, purchase project materials from nearby suppliers. This will reduce emissions for transport. By purchasing materials locally, well decommissioning activities are also helping to sustain the local economy. 5.2 Waste Minimization The proposed monitoring well decommissioning activities are anticipated to generate a small amount of waste. Metal and concrete materials will be recycled as much as possible. An attempt will also be made to reuse equipment through decontamination procedures if possible. Waste minimization will be an integral part of the execution of this Work Plan. 5.3 Occupational Health and Safety The highest priority of this project will be to have zero health and safety incidents. Raising occupational health and safety awareness promotes sustainable human resources for the life of the project. As such, this project will require a project-specific HASP, and the field team will conduct daily safety meetings. FES0817211625BAO
