CC - Item 3F - Installation of Red Curb at 3 Locations - Access to EPA Mandated Groundwater Extration WellsROSEMEAD CITY COUNCIL STAFF REPORT TO: THE HONORABLE MAYOR AND CITY COUNCIL FROM: JEFF ALLRED, CITY MANAGER DATE: AUGUST 14, 2012 SUBJECT: INSTALLATION OF RED CURB AT 3 LOCATIONS — ACCESS TO EPA MANDATED GROUNDWATER EXTRACTION WELLS SUMMARY The Traffic Commission recently reviewed a request to install parking restrictions at 3 locations in conjunction with a U.S. Environmental Protection Agency (EPA) groundwater cleanup effort. The El Monte Operable Unit (EMOU) is a portion of the EPA/San Gabriel Valley Superfund Project — a legally mandated groundwater cleanup effort in several locations throughout the San Gabriel Valley. Such cleanup activities are being conducted as a result of years of illegal dumping of toxic materials into nearby waterways, which ultimately contributed to the contamination of both shallow and deep groundwater supplies. As part of these court- mandated activities, former polluters are being required to fund efforts to install cleanup extraction wells that are designed to remove contaminated ground water. The City is not a participant in the cleanup activities. However, due to the location of the contaminated groundwater, it is necessary to permit the installation of cleanup wells within the City in order to effectively remove the contamination. Based on these cleanup efforts, the EPA/EMOU will install 3 groundwater cleanup extraction wells in the City. Once installed, these wells will be located in public right -of- way areas (sidewalk or parkway areas) and will require regular access from maintenance vehicles and personnel. Due to these access requirements, red curbing is requested to allow maintenance vehicles uninterrupted availability to each well site. Staff Recommendation It is recommended that the City Council approve the Traffic Commission's recommendation to install red curbing at 3 locations — adjacent to 3787 Brookline Avenue, 9326 Ralph Street, and 9448 Guess Street — upon installation of groundwater cleanup wells. The El Monte Operable Unit (EMOU) is a portion of the U.S. Environmental Protection Agency (EPA) San Gabriel Valley Superfund Project — a legally mandated groundwater ITEM NO- City Council Meeting August 14, 2012 Page 2 of 3 cleanup effort in several locations throughout the San Gabriel Valley. For years, efforts have been made to clean up groundwater supplies that resulted from years of dumping toxic materials into nearby waterways. Such dumping ultimately contributed to the contamination of groundwater supplies. It is important to remember that the City is not a participant in the cleanup activities. However, due to the location of the contaminated groundwater, it is necessary to permit the installation of cleanup wells within the City in order to effectively remove any contamination. The EMOU is located in eastern portions of the City — south of Valley Boulevard, north of the Interstate 10 freeway, and east of Rosemead Boulevard. Using modeling software, geotechnical engineers have been able to identify specific well locations that will be used to extract contaminated water. Once extracted, this water would be pumped via pipelines to a water treatment facility, cleaned, and then be made available for reuse. In total, there are 3 extraction wells locations in Rosemead adjacent to the following properties — 3787 Brookline Avenue, 9326 Ralph Street, and 9448 Guess Street. Each location has been studied and identified as an optimum location to remove contaminated groundwater supplies. Over the last year, representatives from the EPA/EMOU have taken steps to inform the public regarding the contaminated groundwater and mandated cleanup activities. These steps have included the preparation of a California Environmental Quality Act (CEQA) Initial Study, individual meetings with residents, several publicly noticed meetings, and a community workshop. Meeting notices were mailed to residents in a 300 foot radius in advance of each public meeting and workshop. As a result of this public involvement, input was received from residents and according to the EPA/EMOU representatives, has resulted in changes to some of the well locations. In July, the Traffic Commission reviewed this item and asked several questions related to well construction, operation, and maintenance activities. Further, the Commission asked about outreach activities that had been conducted. There were no public comments issued at the meeting regarding this project. As planned, the 3 extraction wells will be located in the public right -of -way adjacent to residential properties (see Attachment 1). The construction of the wells will last several weeks. After construction, at -grade utility boxes will be installed that maintenance personnel will need to be accessed for operational checks or repairs. The wells will be monitored daily, requiring a need for parking restrictions in order to maintain clear access to each well site. It is anticipated that the well construction will be completed in 3 phases starting this fall and lasting nearly 1 year. Red curbing would be installed at each location following the completion of construction. Once in place, it is estimated that the wells will remain in operation for over 20 years. City Council Meeting August 14, 2012 Page 3 of 3 FINANCIAL REVIEW The cost for red curbing at this location will be covered through the EPA superfund project. Future maintenance and painting will be the responsibility of the well operations personnel. ENVIRONMENTAL REVIEW The project is categorically exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15301 (a) of the CEQA Implementing Guidelines. PUBLIC NOTICE PROCESS This item has been noticed through the regular agenda notification process. A notification postcard was delivered to properties within approximately 300 feet of each location prior to the Traffic Commission review of this item. Property owners in the area not able to attend the Commission meeting were also encouraged to submit written comments to the Public Works Department. Additional public outreach meetings and door -to -door meetings were also conducted with adjacent residents.

O R NOTICE OF CONSTRUCTION ACTIVITY The purpose of this notice is to inform you that construction activities associated with the El Monte Operable Unit portion of the U.S. Environmental Protection Agency (EPA) San Gabriel Valley Superfund Sites will be occurring in the vicinity of your residence. The East Side Performing Settling Defendants (ESPSDs), under agreement with the EPA, are preparing to install three groundwater production wells and associated pipelines in the City of Rosemead. The wells and pipelines will be installed as part of a project to clean up groundwater within this area. Geosyntec Consultants (Geosyntec) and their subcontractors will be performing this work on behalf of the ESPSDs. Construction activity will occur in three phases; well installation, pipeline construction, and production well equipping. Construction activities will result in the partial closure of roads during portions of the project. Work will be performed on weekdays between the hours of 7 AM to 5 PM using a truck - mounted drill rig and backhoe. The construction activities do not expose anyone in the area to any chemicals that may be present in the groundwater. Production Well Installation During well drilling, soil and water removed from the borehole will be contained and then removed from the site when the project is completed. The street and sidewalk will be cleaned after the drill rig is removed and repaired as necessary. Sound reducing enclosures will be constructed around the drilling operation to minimize noise impacts on surrounding residents. Well testing will occur after installation and will be completed during the day using a smaller truck and generator. The EPA has granted permission to discharge well testing water from a hose to the nearest storm drain catch basin at each well location. The groundwater production wells will be located at 3787 Brookline Avenue, 9326 Ralph Street, and 9448 Guess Street. Groundwater production well installations and well testing are expected to begin in early August, 2012. The following schedule is currently anticipated: Well DEW -1 (3767 Brookline Avenue) August and September 2012 Well DEW -2 (9326 Ralph Street) September and October 2012 Well DEW -3 Installation ( 9448 Guess Street) October and November 2012 Pipeline Construction The pipelines connecting the three wells will be constructed along Ralph Street, Rio Hondo Avenue, Guess Street, and Strang Avenue and will tie into an existing pipeline located near the corner of Strang Avenue and Valley Boulevard (see map below). During pipeline construction, minimal volumes of soil that are displaced during trenching activities will be contained and then removed from the site as pipeline sections are completed. Repairs to the street will be done at the completion of each pipeline section. Pipeline installation activities are anticipated to occur between February and June 2013. , Well Equipping Well equipping includes below ground vaults and above ground vent enclosures, well head enclosures, and telemetry poles in the immediate vicinity of the production wells. During well equipping, minimal volumes of soil that are displaced during excavation activities will be contained and removed from the site. Repairs to the street, sidewalk, and parkway will be done after well equipping. Well equipping is anticipated to occur between April and June, 2013. Community Outreach A community information meeting will be held in the Savannah School Cafeteria between 6PM and 8PM on June XX, 20f2. Residents are welcome to stop by anytime during the meeting to learn about the project and discuss any questions or concerns with the project staff. Refreshments will also be served.
