3. Environmental Checklist San Leandro Treatment Wetland IS/MND 3-42 February 2024 with Kinder Morgan, in accordance with their Developer Handbook.33 Project plans must be provided to Kinder Morgan at least six weeks before construction commencement to allow for the receipt of an approval letter, which may contain specific procedures to be followed. Additionally, before any excavation occurs near the pipeline, the City or its contractor must notify 811 at least three days before the excavation. Excavation or ground disturbance in proximity to active pipelines requires the implementation of protocols for informing the owners/operators in the event of an accidental rupture, followed by the implementation of shutdown procedures. In line with the Developer Handbook, the City will promptly notify Kinder Morgan’s Operations Supervisor or Area Manager if damage occurs to a pipeline. If the damage results in releasing any flammable, toxic, or corrosive substance that poses a risk to life or property, the City will immediately contact 911. Moreover, if the damage affects a pipeline not owned by Kinder Morgan, the owner or operator of that pipeline must also be notified. c) Within One-Quarter Mile of Schools: No existing or planned elementary, middle, intermediate, or high schools are within 0.25 miles of the Project site. The nearest school facility is Garfield Elementary School, approximately 0.95 miles southeast of the Project site. As discussed above, the Proposed Project does not anticipate releasing hazardous emissions or handling acutely hazardous materials, substances, or wastes in significant quantities. Construction activities associated with the Proposed Project would use a limited amount of hazardous and flammable substances/oils during heavy equipment operation for site excavation, grading, and construction. The amount of hazardous chemicals present during construction would be limited and would be in compliance with existing government regulations. During operation, the Proposed Project site would not require the use, storage, disposal, or transport of large volumes of hazardous materials that could cause severe environmental damage in the event of an accident. Although hazardous substances would be present and utilized in limited amounts within the Project site, they would typically be present in small quantities and can be cleaned up without affecting the environment. In addition, the Project site is not within 0.25 mile of any schools. Therefore, there would be no impact on potential exposure of hazardous emissions or acutely hazardous materials, substances, or wastes within one-quarter mile of a school. Impact Designation: Less than Significant Impact d) Hazardous Materials Sites According to Government Code Section 65962.5: While there are several release sites listed near the Project area, and some are included in the "Cortese" list as per Government Code Section 65962.5, the Project site itself is not on this list.34 Therefore, the Proposed Project would have less-than-significant impacts associated with lists of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Impact Designation: No impact 33 Kinder Morgan. 2021. Developer Handbook: Guidance for Working Near or Adjacent to a Pipeline.
