1. Conventional Facilities Overview

1.1 Introduction

The Electron-Ion Collider (EIC) Conventional Facilities provide the buildings (referencing the table in section 1.2 below), utility systems and site infrastructure systems necessary to enable installation and operation of the particle accelerator, storage rings, and target instruments. The Conventional Facilities must be designed and constructed to enable the performance of the most advanced lepton-hadron collider ever built. Furthermore, the Conventional Facilities must be constructed on a schedule that enables installation of the accelerator systems in accordance with the overall project schedule.

1.2 Project Description

The EIC project leverages the accelerator tunnel and related existing buildings constructed for the

Relativistic Heavy Ion Collider (RHIC) built in the late 1970’s. Hence, the primary EIC facilities are located adjacent to the existing Interaction Regions (IR), typically reinforced concrete structures, located at the 2 o’clock, 4 o’clock, 6 o’clock, 8 o’clock, 10 o’clock, and 12 o’clock positions. Smaller buildings are located outside of the berm and tunnel profile at the 1 o’clock, 3 o’clock, 5 o’clock, 7 o’clock, 9 o’clock, and 11 o’clock positions to house power supplies serving magnet systems within the tunnel. The EIC project is intended to be operated with a schedule: 9 months on (Oct-Jun) and 3 months off (Jul-Sep).

The largest EIC building is located at 10 o’clock. Building 1010C is located adjacent to the IR at the

10 o’clock position and houses the significant quantity of RF equipment providing over 10 MW of energy to the RF cavities located within the existing IR building.

The project also includes expansion of Buildings 631 and 638 to add two additional 69 kV/13.8 kV transformers and associated switchgear to support new EIC power supplies.

2.3 Geotechnical Survey

An on-site geotechnical investigation by GEI Consultants Inc. P.C., which included drilling of geotechnical investigation borings, was completed in 2020. Additionally, a supplemental draft geotechnical report prepared by GEI was completed in May 2024. Refer to Structural Section 5 for additional detail related to the geotechnical evaluation.

2.4 Topographical Survey

HDR utilized the services of H2M and a NYS Licensed Land Surveyor to prepare existing conditions mapping of the various building sites around the ring and for the high voltage power supply corridor.

The updated mapping was collected from January through March 2024 and it includes topography at a 1-foot contour interval, existing roads, existing buildings, vegetation, and cover, as well as water course locations (i.e., associated wetlands), and delineated federal and state wetlands (locations which were provided in a KMZ file by Brookhaven National Laboratory), etc.

The updated survey utilizes NAVD 1988 for the vertical datum as well as NAD83 NY State Plane, Long

Island, US Foot for horizontal datum. The survey is coordinated with survey controls and monuments as established by Brookhaven National Laboratory.

Field topography and associated utility information was obtained at the building sites using a combination of field crews, robotic equipment, and GPS instruments. A supplemental portion of existing contour information was obtained for the high voltage power supply corridor using topography supplied from National Oceanic and Atmospheric Administration (NOAA) based sources including

LIDAR that was obtained in 2014. The field survey work is in accordance with the New York State

Association of Professional Land Surveyors Code of Practice. The LIDAR data obtained for the high voltage power supply corridor was prepared with a vertical and horizonal accuracy of +/- 1 foot.

Portions of the Building sites at 1001A, 1004G, 1010C, 1010D, 1010E, 1011A and Building 638A

(Substation Extension) currently lack adequate topographic survey information to complete the final grading plan. However, an extension of the surveying areas has been approved and the additional areas will be collected and mapped to incorporate into the issue for construction package.

2.5 Existing Conditions

The location of the streambanks along the Peconic River as well as the related FEMA 100-year floodplain area are depicted based on available GIS data obtained by HDR. Information relative to existing site utilities has been obtained from as-built record drawings as provided by BNL. In addition, the utility locations are based on coordinating the as-built records with physical site features, as obtained during the performance of the field surveys.

2.6 Water Supply

Domestic water is distributed around the current RHIC ring. An updated site water report was provided indicating the available water flows and pressures. The model is based on BNL hydraulic modeling which is updated on at least an annual basis. In general, the flows are adequate for domestic purposes and in some areas insufficient for fire flows.

2-3

In response to RFI 222, BNL did provide a copy of the annual water system report (dated January

2025) along with some additional simulations. The following table 2.6.1 provides an overview of the available flows at 20 psi and static pressures at no flow conditions. It is noted that there are multiple test points with available fire flows below the maximum expected fire flows.

It is noted that prior to the implementation of new water mains/services, a full set of engineering plans, specifications and engineering report must be approved by BNL Energy and Utilities as well as Suffolk

County Department of Health Services via DOH-348 submittal.

2.7 Sanitary Sewer

Existing sanitary sewer is available at several buildings around the ring. Given that the buildings are spaced relatively far apart and the change in grade around the ring is not significant, the majority of the sanitary sewer relies on remote pumping stations at each building. The pump stations discharge into a force main that flows to the next station which then pumps to the next station in series. This is the case going counterclockwise starting at building 1012 to 1010 and onto 1008. From 1008 there is a force main that leads to a gravity manhole close to 1007. The sanitary sewer then services Buildings

2-4

1006 and 1005 via gravity piping. From the other direction going clockwise from Building 1002 there is a pump station and force main that runs around the ring to 1003 and onto 1004. There is a section of gravity sewer running in between 1004 to 1005. From 1005 and going easterly the sewer flow is pumped away from the ring.

As new buildings are brought online, only certain ones will be occupied for a sufficient enough time to warrant restroom facilities. Examples of buildings of this type are proposed building 1010D and the

Substation building 638A. As such, a grinder pump station will be added near each building. For

1010D, the force main will be run to the existing pump station located adjacent to Building 1010A. For the proposed Substation Extension Building 638A, an ejector pump will be added near this building to run to the existing sanitary sewer located within the intersection of East 5th Avenue and Railroad

Avenue. Profiles for these force main runs are included within the plan set. The locations of any air or vacuum relief valves at high points are similarly noted on the profiles.

Several buildings will be served by adjacent cooling towers, including 1001A, 1003A, 1005T, 1006G, 1007A, 1009A, 1010D, 1010E, and 1011A. The blowdown water from the cooling towers will be discharged to the sanitary sewer system. The tower water blowdown rate to sanitary sewer is controlled to maintain the maximum cycles of concentration based on tower water hardness and sulfate concentrations, as indicated by condenser water conductivity. The discharge of blowdown water is further described in Section 7.5 under Plumbing.

Table 2.7-1 indicates the estimated demand of the cooling towers and the related blowdown wastewater flow from the cooling tower locations. This estimate is for preliminary planning purposes and will be refined during the final design process. 1006K is related to the crab cavities which is at a concept design stage and flow rates are preliminary.

2.8 Stormwater Management

The site is previously developed and there are existing wetlands and other sensitive features that could be impacted from the project improvements throughout the site. For example, the impervious coverage for the overall site will be increased due to this project. Therefore, the quantity of stormwater runoff will be increased, and the quality of the runoff is expected to be degraded without implementation of best management practices (BMPs). Since site disturbance is over 5,000 SF, compliance with EISA Section 438 is required and will be included in the stormwater evaluations. The overall approach is to use planning, design, construction, and maintenance strategies to maintain or restore the predevelopment hydrology of the property in terms of temperature, rate, volume, and duration of flow. Low Impact Development (LID) solutions (also referred to as “green infrastructure”) will be incorporated in the form of infiltration practices (i.e. either infiltration basins or dry wells or similar).

2-5

Each building site will be treated separately for purposes of stormwater management. Areas of new buildings/structures and new pavement will be included in the drainage calculations. Landscaped or lawn areas abutting new impervious surfaces will be evaluated to determine whether stormwater management for these areas are required. Site grading will direct stormwater to low points at convenient locations within the site (away from buildings and as far from other utilities as possible), where the stormwater will be collected within yard inlets, catch basins, or drywells with open grates.

The stormwater will then be directed to a dry well system or infiltration basins where infiltration into the soils will occur. Areas of high groundwater will utilize concrete leaching galleys or similar practices for infiltration.

The controlling requirements for stormwater design elements on this project are those spelled out with the New York State Stormwater Design Manual. The Manual dictates that a minimum volume be treated for the purposes of water quality. Furthermore, there are several measures relating to water quantity that require the design to mitigate existing conditions. To meet the requirements of the

Manual, each site is required to have an infiltration test performed within the disturbance area.

Buildings 1001A, 1009A, 1010 Cluster, 1011A, and the 638A (Substation extension) are missing infiltration data; therefore, a full drainage design cannot be completed at these locations. Furthermore, considering further revisions to be determined, a full drainage analysis has not been performed at this time. To account for this, conservative assumptions on soil infiltration rates have been included in the design. In addition, the performance of additional infiltration testing has been approved. Once the additional data from these areas has been collected, it will be incorporated as part of the issue for construction package. Stormwater volumes provided meet the requirements of the New York State

Stormwater Design Manual and EISA Section 438. The drainage systems for each individual site will capture and infiltrate a minimum of 1.5 inch of stormwater runoff over the tributary area without system overflow. These systems may need to be upsized once a full stormwater analysis is performed.

Buildings 1006H, 1006I and 1006K are related to the crab cavities which is at a concept design stage, so flow rates are not yet available.

Per the New York State Stormwater Design Manual, water quantity must be addressed for three separate criteria. This includes channel protection volume (CPv) based on the 1-yr, 24-hr storm event to protect stream channels from erosion, overbank flood control (Qp) and extreme flood control (Qf) being fully managed on-site. Table 2.8.1 indicates the pre- and post-development peak runoff rates at each project site. With the implementation of stormwater facilities with the ability to infiltrate and attenuate flows, water quantity has been adequately addressed for the 1-, 10-, and 100-yr storm events at each individual site. The breakdown of the storm events for each area can be found below.

The table indicates that the post-development flow rates will not exceed the current pre-development rates at each of the sites. Please note that the sites may have multiple sub-watersheds. These have been added together for the total flow at the site. Please see plans for sub-watershed breakdown.

The Peconic River intersects the existing RHIC ring in two locations. There is a 100-year (1% chance recurrence interval) floodplain associated with the Peconic River at the site. FEMA has designated the floodplain as a Zone A with no base flood elevation yet determined. All facilities will be cited to be outside of the existing floodplain. HDR will follow the adopted guidance as specified in the NYC

Climate Resiliency Design Guidelines (Version 4.1 dated May 2022), since BNL has adopted the guidance for related infrastructure planning.

Pursuant to the NYC Climate Resiliency Design Guidelines, a Design Flood Elevation (DFE) for proposed structures had to be calculated. The DFE is calculated by adding the Base Flood Elevation

(BFE), a freeboard of 24 inch, and a sea level rise adjustment of 28 inch.

The Base Flood Elevation was calculated pursuant to FEMA’s “Managing Floodplain Development in

Approximate Zone A Areas: A Guide for Obtaining and Developing Base (100-Year) Flood Elevations”.

The values for the freeboard and sea level rise adjustment are based on preset values from a table in the NYC Climate Resiliency Design Guidelines. The freeboard value of 24 inch is for any length of design life. For our project, the expected design life is 50 years. The sea level rise adjustment value of 28 inch is for structures whose end of useful life will be approximately in the 2080’s (2070 -2099).

Each building containing cooling towers will be provided with storm drainage sources near the cooling plants. These drains will collect runoff and blowdown from cooling towers, and gravity drain to new pump stations which will interconnect to the existing on-site storm drainage piping or connect to existing pump stations where applicable.

Additional site features, such as retaining walls and sloped landscaped areas, will be considered during the upcoming design to facilitate proper tie-in to existing grading and to minimize site impacts.

2.9 Erosion and Sedimentation Control

Erosion and sedimentation control systems will be installed and utilized for the duration of the construction phase of the project. The estimated limit of disturbance (LOD) area is anticipated to be approximately 34.9 acres which is well above the threshold of one acre that would trigger the need for obtaining SPDES coverage and the related filing of a Notice of Intent (NOI). In terms of actual tree removal, the area is somewhat less at 24.9 acres of trees requiring removal. It is noted that this considers clearing needed for site access, grading, utility extension and the forming of a minimum 30’ buffer around the high voltage power line corridor as well as all proposed structures in accordance with the BNL adopted wildland fire prevention guidance which is based on NFPA 1140.

Given the scope of the project, a Stormwater Pollution Prevention Plan (SWPPP) that consists of an erosion and sediment control plan and Post-Construction Stormwater management including the design of related water quality and quantity controls/best management practices (BMPs) will be required. The NOI procurement is done through e-filing using a NYSDEC portal. It is anticipated that permit filing and payment of any related fees will be performed by either BNL or the selected contractor.

The plans will adhere to the requirements of the New York Standards and Specifications for Erosion

Control. Silt fencing and stabilized construction entrances will be installed prior to the commencement of construction activities. Disturbed areas within the construction site will be stabilized as soon as practical and subsequently maintained with appropriate methods to minimize erosion of exposed earth. Temporary seeding, mulching, or crushed stone will be used to achieve stabilization where required. The primarily sandy soils do not have a high probability of wind or hydraulic erosion, meaning that the erosion controls likely will be minimal and typical of local construction activities.

2.10 Grading

The site will be graded to provide positive drainage away from the buildings and ensure that stormwater runoff does not adversely affect surrounding sites. To the greatest extent possible, grading will follow the slopes indicated.

Item Gradient

Longitudinal grades of roadways with curb and gutter Min. 1.0%

Traverse grades of roadways with curb and gutter Min. 2.0%

Longitudinal grades of roadways without curb and gutter Min. 0.0%

Traverse grades of roadways without curb and gutter Min. 2.0%

Concrete pavement parking areas Min. 1.5% Max. 5.0%

Curb and Gutter/Valley Gutter Min. 1.5% Max. 5.0%

Bituminous pavement in parking areas Min. 1.5% Max. 5.0%

Handicap areas in parking areas Max. 2.0% (any direction)

Concrete sidewalks Min. 1.0% Max. 5.0%

Concrete landings Max. 2.0%

Paved concrete ditches Min. 0.25%

Unpaved ditches Min. 2.0%

2-8

In addition, grading to provide earthen shielding will be necessary for Building 1010C as noted on the plans.

BNL and the contractor will obtain the services of an independent soils laboratory to conduct in-place compaction tests throughout construction.

Topsoil will meet the requirements of NYSDOT Topsoil Section 713- 01. Topsoil will be spread to a compacted depth of 4-inches in all disturbed earth areas.

2.11 Access, Traffic, and Parking

The main entrance to the EIC facilities is from the existing ring road (Renaissance Road) that runs parallel with the existing tunnel. No substantial increase in traffic levels is expected as most of the buildings are unmanned or are staffed at similar levels to current operations. Service vehicles as well as personnel vehicles will have access from the existing road network. Additional access road extensions and turn around locations will be added in proximity to Building 1010C.

Per BNL Fire Code official’s direction, access drives were evaluated regarding excessive length which would require a tee turnaround. However, no facility dead end drives are more than 300 feet therefore no tee turnaround’s have been added. AutoTurn simulations have been performed on all proposed roadways using the specifications for fire apparatus equipment as provided by BNL. Roadways are designed to provide unencumbered access to facilities for firefighting purposes.

With regular occupants by daily staff being limited to Building 1010C, there are no significant requirements for parking lots adjacent to the EIC buildings. It is anticipated that three to four spaces may be provided at the power supply buildings, three to four spaces at Buildings 1004G and 1006G, and six spaces at Building 1010C for service vehicles. This includes one ADA accessible parking space with associated van loading zone at each building.

Pavement design construction standards will conform with the New York State, Department of

Transportation, and “Standard Specifications" (latest edition) Reference is made to the related

Standard sheets for further details.

All new road and surface parking lot pavements will be asphalt, concrete, or porous concrete.

Pavement in loading areas will be reinforced heavy duty concrete. The cross-sectional design of all traffic pavements will be based on the recommendations set forth in the geotechnical report. The edge of all roads and parking lots edges will typically be absent of concrete curb and gutter. This will facilitate sheet flow of stormwater runoff into grassed areas.

Sidewalks in or adjacent to parking lots or loading areas will be either standard duty concrete or gravel as indicated on the plans.

Aggregate base for pavements will be naturally or artificially graded mixture of crushed gravel or crushed stone. The base will be compacted between 95 and 100%. The subgrade under pavements should be moisture conditioned between optimum and plus four percentage points above optimum moisture content and compacted to a minimum 95% of the maximum dry density in accordance with

ASTM D 698. These criteria will be confirmed once the Geotechnical Report is made available.

2-9

Hot mix asphaltic concrete will comply with mix design category per New York State, Department of

Transportation, Standard Specifications, including latest updated versions.

Line paint will be non-reflective, white paint conforming to NYSDOT TT-P-115E. Wayfinding and traffic control related signage will be detailed within an upcoming design submittal.

2.12 Pump Station Design

New pump stations will be located across the site dedicated for sanitary and storm flows leaving the new buildings and cooling tower plants. New pump stations will be provided for the following buildings:

638A, 1001A, 1003A, 1005T,1006G, 1009A, 1010D and 1011A, and a relocation of the existing SP-2 at 1005. It is noted that at 1007A, sanitary sewer collection is nearby and allows for gravity drainage.

As such no pump station is necessary.

Each pump station will be provided in an underground concrete wet well with a duplex pump set. Each pump shall be sized for full flow, with float level controls and control panels with level, run and fault alarming. Force main piping leaving the wet well will enter a valve vault where each pump will have dedicated isolation and check valves prior to combining and discharging to the existing piping systems.

Where required, new pump stations will be sized to account for the positive head pressure imposed on the current force main to operate in conjunction with the existing force mains. Check valves will prevent backflow of any pumping station working against another.

An existing pump station (SP-2) is currently located underneath the proposed location for Building

1005T. The pump station will need to be relocated: new pumps will be provided to match the existing configuration and capacity. All associated infrastructure and connections related to the existing pump house will be removed and relocated.

A new pump station will also be provided for the existing 7200-gallon transformer oil containment pit.

The pump station will be an oil minder system, pumped out to the storm sewers. The new site and existing site transformers will be piped to the existing oil containment pit, where an oil weir will act as a separator in case of any oil spill. Storm flow will drain across the weir to the oil minder station where the pump sensors will act as a redundant source of oil detection upon any emergency transformer discharge situations during a storm event.

2.13 Crab Cavity Design

Within the 1006 locus of the EIC tunnel, two berm top enclosures will be installed. The purpose of the enclosures is to house equipment above the tunnel to maintain the alignment of the beams of both the

Hadron Storage Ring and the Electron Storage Ring. The equipment within the buildings includes RF power amplifiers and Low Level Radio Frequency (LLRF) controls. Related utility support infrastructure including chilled water closed loop cooling (process cooling), electric substations, domestic water, compressed air, and telecommunications will be provided in adjacent support facilities.

Access to the facility will be accommodated by driveways and small parking areas will be extended from Thompson Road or other nearby access locations. Figure 2-13.1 depicts the locations of existing or relocated fire hydrants along with staging points for emergency equipment to access the berm top enclosures. The NYS BC Section 503 requires access to be available within 150 feet of a building that is not protected by sprinklers. Given the configuration of the building as an elongated rectangle, access

2-10 shall be available from two of the longer sides of the building. The figure shows the radial distance from the staging points as being within the required 150 feet. Since the buildings are to be equipped with sprinklers, this distance is deemed to be conservative.

3.1 Design Criteria

The fundamental design criteria for the Electron-Ion Collider (EIC) Conventional Facilities are to provide functional, durable structures that will protect and support the systems and equipment that enable the operation of the Electron-Ion Collider. These buildings must provide protection from the elements, facilitate access for maintenance and replacement activities, supply stable environmental conditions in terms of temperature and relative humidity, and include appropriate radiation shielding where radiation hazards exist.

With few continuously occupied spaces required, the majority of built spaces are anticipated to represent an industrial building type with only limited exceptions were dictated by frequent use by

EIC personnel (control rooms, break rooms, the laser lab) or the specific requirements of certain technical equipment.

3.5 Building Construction

3.5.1 Building Envelope

The building envelopes will be designed to meet heat transfer coefficients to meet the Energy

Conservation Code of New York (ECCNY). Brookhaven National Laboratories are located in Climate

Zone 4A of the ECCNY. Commercial buildings are required to comply with one of the following:

1. ASHRAE Compliance Path: The requirements of ANSI/ASHRAE/IESNA 90.1, as amended by 19 NYCRR Part 1240.

2. Prescriptive Compliance Path: The requirements of Sections C402 through C405 and C408 of the ECCNY. In addition, commercial buildings will comply with Section C406, and tenant spaces will comply with Section C406.1.1 of the ECCNY.

3. The requirements of Sections C402.5, C403.2, C403.3 through C403.3.2, C403.4 through

C403.4.2.3, C403.5.5, C403.7, C403.8.1 through C403.8.4, C403.10.1 through C403.10.3, C403.11, C403.12, C404, C405, C407 and C408 of the ECCNY. The building energy cost must be equal to or less than 85 percent of the standard reference design building.

Presuming that the EIC project will pursue the Prescriptive Compliance Path, the following minimum code requirements would apply (partial list):

1. Roofs

• Insulation above roof deck: R-30 continuous

2. Walls Above Grade

• Metal buildings: R-13 with R-13 continuous

• Metal framed: R-13 with R-7.5 continuous

3. Walls Below Grade

• Below-grade wall: R-7.5

4. All Buildings: 30 feet clearance of trees around the buildings as part of Woodland Wild-Fire control

3.5.2 Building Construction Types

Multiple construction types are under consideration for the EIC buildings, including:

• Pre-engineered Metal Building System which are typically a delegated design that are erected at site by a single supplier-subcontractor. The exterior wall system will consist of 4 inch, 22 GA insulated metal panels (R-29) installed on “Z” or “C” girts spanning between structural frame members. The gable roof system will be comprised of metal roof liner, vapor

3-4 retarder, rigid insulation (R-30 minimum) and a 24 GA, PVDF coated metal roof panel.

Interior partitions will be constructed of gypsum board on metal studs at 16 inches on center.

• Concrete slab-on-grade, steel structural frame for vertical and horizontal loads, insulated metal panel walls, concrete on metal deck for intermediate floors, metal deck with cover board, rigid insulation, and single ply roofing. Interior partitions will be constructed of gypsum board on metal studs at 16 inches on center.

3.5.3 Noise Criteria

Two specific areas within the EIC project have been identified as requiring specific acoustical treatments. The cryogenic plants (Buildings 1006G and 1010E) are hearing protection areas with the compressors generating sound pressure levels above 85 dBA. With the understanding that operating procedures will dictate the use of double hearing protection, an industrial grade sound absorbing material will be specified for the interior surfaces of these buildings.

Additionally, pumping equipment located in cooling water pumprooms is anticipated to produce significant sound pressure levels and will be planned to achieve NC-50 via the selection of sound absorbing materials once the specific characteristics of the planned equipment are understood.

3.5.4 Interior Construction

The EIC buildings are predominately equipment enclosures and as such will have interior spaces dominated by exposed structural elements with only limited spaces such as control rooms, the laser lab, break rooms, etc. having nominally commercial interior finishes such as vinyl composition floor tile, gypsum board walls, and acoustic tile ceilings.

3.5.5 Interior Finishes

The EIC buildings, as stated previously, are predominately equipment enclosures with limited occupied spaces such as touchdown offices, control rooms, a laser lab and break rooms, etc.

material finishes and details will be simple, durable, and high quality. Specific colors and materials will be investigated and determined during the project’s development. All Buildings will have Class A interior finish and roof per DoE requirements.

3.5.6 Signage

The exterior signage will be limited to one side of the structures in scope. The signage will be designed to incorporate a design accent which signifies the building placement along the ring of the collider, then four numbers and one letter to confirm the building address. The size and placement of the sign message is based on visibility along the maintenance road. Aiding in the visibility, contrasting colors will be used which are based on the Brookhaven brand standards. An elevation of each structure will be provided showing the sign message, sign design information as well as the mounting location. None of these signs will be illuminated.

3-5

The interior signage will incorporate the fundamental components necessary to satisfy all room, regulatory and code requirements. This sign type is based on the current signage system in place. Due to the small footprint of each building, there isn’t a need for wayfinding information.

The sign types will be limited to the following: Fire extinguisher identifier, room identification, stair and stairwell identifier as well as restroom signage. None of the signs will have the capability to be updatable. Where appropriate, signs will include raised copy and Grade II Braille components with permanent and specific functions as specified by the 2010 SAD (ADA) code. The raised text and Braille will be produced using the latest 3D printing technology which will provide a better-quality result than signage of the past which used either applique or photopolymer. Where appropriate, signs will include raised copy and Grade II Braille components with permanent and specific functions as specified by the 2010 SAD (ADA) code.

Sign location plans for each structure will be provided. Each plan will incorporate a location marker/lozenge with a leader line pointing to each sign location identified using both a sign location number and sign type.
