SUBJECT: Consideration and possible action to issue an encroachment permit to Jacobs Engineering for purposes of soil and groundwater sampling at Caruthers Park on behalf of Kinder Morgan and the development of a licensing agreement with Kinder Morgan for the installation and long-term access to monitoring wells at Caruthers Park.
DATE: January 22, 2024
EXECUTIVE SUMMARY
Receive input from the City Council regarding the request from Jacobs Engineering (on behalf of Kinder Morgan) for an encroachment permit to bore on City property (Caruthers Park) for the purpose of soil and groundwater sampling as part of the environmental investigation associated with the damaged Kinder Morgan pipeline discovered in December 2022. Additionally, Kinder Morgan is seeking a licensing agreement with the City for the installation of four monitoring wells, three of which will be on City property and one will be on Caltrans property that will require access through City property.
RECOMMENDATION TO CITY COUNCIL
1) Authorize the City Manager, or designee, to issue an encroachment permit to Jacobs Engineering for boring on City property (Caruthers Park) for soil and groundwater sampling; and
2) Authorize the City Manager to negotiate a license agreement with Kinder Morgan, in a form approved by the City Attorney, for the installation and access for ongoing monitoring of three monitoring wells on City property and access through City property to one monitoring well on Caltrans property; or
3) Alternatively, discuss and take other action related to this item.
FISCAL IMPACT
Fees for the encroachment permit will be based on the City’s current fee schedule for boring and for recreation facility rental (baseball field), preliminarily estimated to be $5,752.00. Fees associated with the licensing agreement are unknown at this time but will be based on the installation of the monitoring, long-term access to the individual well sites and other appropriate impacts related thereto. The license agreement will be brought back to the City Council for approval once negotiated. -1-
Staff Report – Kinder Morgan and Jacobs Engineering Request for Encroachment Permit and Licensing Agreement
January 22, 2024
DISCUSSION
In December 2022, Kinder Morgan discovered a damaged section of subsurface 16-inch pipeline in the area immediately southeast of Caruthers Park on property owned by Los Angeles County Flood Control and Caltrans. Following emergency repairs to this section of pipeline, Kinder Morgan is required by the State to conduct an environmental investigation in the surrounding area, which includes the installation of monitoring wells. Kinder Morgan has hired Jacobs Engineering to conduct this investigation. Jacobs Engineering has submitted a Letter of Intent (attached) to the City related to the investigation. The scope of work proposed by Jacobs in the LOI is broken into two separate phases described below.
Phase 1
Jacobs Engineering, on behalf of Kinder Morgan, is seeking an encroachment permit from the City to access Caruthers Park to conduct boring operations in order to sample soil and groundwater conditions in the area. This work would consist of using a drilling rig in the southeast corner of Caruthers Park as evidenced by Figure 1 of the Letter of Intent. The work would commence on January 30, 2024, and is expected to last five days, weather permitting. Following the boring operations, each location will be returned to its original condition.
Phase 2
This phase includes the development and installation of three monitoring wells on City property and proposed access to a fourth monitoring well on Caltrans property through Caruthers Park. The development of the monitoring well sites, in conjunction with long-term nature of accessing these areas will be memorialized through a licensing agreement issued to Kinder Morgan.
The proposed locations of the monitoring wells on City property are evidenced by Figure 2 of the Letter of Intent and include (1) the Caruthers Park parking lot, (2) the area just east of the Beach Street cul-de-sac and (3) the area just north of the Palo Verde Avenue cul-de-sac. Once completed, the surface profile of each well location will be a flush-mounted, traffic-rated well box, approximately 1 foot x 1 foot in size. For the monitoring well proposed on Caltrans property just south of the Caruthers Park fence line, Kinder Morgan has requested permission to construct a 10-foot-wide service road comprised of decomposed granite (DG) adjacent to the eastern fence line at Caruthers Park. This service road will provide vehicle access from the end of the Caruthers Park parking lot to the southeast corner of the park where a service gate will be installed by Kinder Morgan within the existing park fence currently in place.
Kinder Morgan anticipates these monitoring wells will be in place a minimum of five years or longer, depending on State requirements. As noted above, due to the long-term nature of this phase, the City Manager will develop a licensing agreement with Kinder Morgan specific to this work and access, identify all applicable fees, costs and rent to be paid by Kinder Morgan under the licensing agreement and will bring the agreement back before City Council for final approval.

Subject Letter of Intent – Kinder Morgan Iron-Wood Environmental Investigation Project Name Kinder Morgan Iron-Wood
Bellflower, California
From Malcolm Thomas/SCO
Alan Van Antwerp/Kinder Morgan
Date
January 10, 2024
1. Introduction
On behalf of Kinder Morgan, Inc. (Kinder Morgan), Jacobs Engineering (Jacobs) presents this letter of intent to the City of Bellflower, to conduct an environmental investigation of petroleum hydrocarbon impacts to soil and, potentially, groundwater from a release of fuel products from a damaged section of a subsurface 16-inch pipeline, located just south of the southern boundary of Ruth Caruthers Park, at 10500 Flora Vista Street in Bellflower, California (Figure 1 and 2). Work is proposed to be conducted within and around Ruth Caruthers Park. Work will be completed in two initial phases, accompanied by long-term access, and monitoring of installed groundwater monitoring wells. Below is a description of work, anticipated project schedule, and long-term access details.
2. Scope of Work
Phase 1:
Kinder Morgan is requesting a short-term encroachment permit to drill soil borings on City of Bellflower property, located at 10500 Flora Vista Street (Ruth Caruthers Park). Jacobs is planning on conducting a Direct Push Technology/Laser Induced Fluorescence (DPT/LIF) survey using a DPT drill rig and Dakota Technologies UVOST® LIF technology at up to four locations. Groundwater and soil samples will be collected from collocated borings immediately adjacent to LIF survey borings (Figure 1).
Soil borings are anticipated to be advanced to a depth of 40 feet below ground surface (bgs), with a 2-inch diameter bore. Borings will be backfilled per Los Angeles County Department of Public Health specifications and California Well Standards, and the surface will be completed like the original condition.
A boring construction diagram is included as Attachment A.
Phase 2:
Kinder Morgan is requesting a short-term encroachment permit to drill and construct three groundwater monitoring wells, in addition to a long-term license agreement for the three monitoring wells on City of Bellflower property (Figure 1). Wells will be installed using a hollow-stem auger drill rig. The planned groundwater monitoring well locations are shown on Figure 2. Proposed locations were selected to avoid existing pipelines and/or utilities.

2 Groundwater monitoring wells will be installed per Los Angeles County Department of Public Health specifications and the California Well Standards. Wells are anticipated to be installed to a depth of approximately 40 feet (bgs), with a maximum diameter of 4-inches. The surface profile of each well location will be completed with a flush-mounted, traffic-rated, 1-square foot well box. A well construction diagram is included as attachment B.
• Install one groundwater monitoring well within the southeastern parking lot of Ruth Caruthers Park (Figure 2).
• Install one groundwater monitoring well just east of the Beach Street caul -de-sac. • Install one groundwater monitoring well just north of the Palo Verde Avenue caul-de-sac (south of the 91-freeway)
To facilitate access to the Caltrans ROW located just south of Ruth Caruthers Park, Jacobs also proposes to access the Caltrans ROW from the southeast corner of Ruth Caruthers Park, via a proposed gate for vehicle access, installed within the existing southern fence line. The proposed gate would be made of similar material of the existing fence line. A construction diagram of the gate is provided as Attachment C. In addition, Kinder Morgan proposes the installation of a vehicle pathway, approximately 10 -feet in width, extending from the northern parking lot, to the southeast corner of the park. The proposed work is summarized as follows:
• Install vehicle access gate within southeastern fence line of Ruth Caruthers Park. • Install vehicle pathway from the parking lot to the proposed gate (decomposed granite material like the baseball diamond in-field), as shown on Figure 2.
3. Proposed Work Schedule
The Phase 1 field investigation is expected to commence January 30th. The project will be conducted on a 10-hour-a-day, 5-day-a-week basis (Monday through Friday, 7:00 AM to 5:00 PM). This work is expected to take approximately 5 business days to complete, The installation of the groundwater monitoring wells and proposed gate and associated pathway in the southeastern portion of Ruth Caruthers Park (Phase 2) is likely to commence in February 2024, requiring 10 to 14 days to complete.
Long-term Access
Groundwater monitoring wells will likely be accessed for 2-3 days on a quarterly basis, for at least the next 5 years, with exceptions to periods of enhanced assessment. The proposed gate in the southeastern corner fence line of Ruth Caruthers Park would be accessed via vehicle or on-foot with a similar frequency to access the groundwater monitoring well on Caltrans property. -4-
