Chapter 2: Project Description

A. INTRODUCTION

The Proposed Project is the Haverstraw Water Supply Project—a water intake, intake pumping

station, water treatment plant, and transmission and distribution mains to be located in the Town

of Haverstraw, Rockland County, New York. The Proposed Project would draw and treat water

from the Hudson River and deliver up to 7.5 million gallons per day (mgd) of potable water to

the existing United Water New York Inc. (United Water) distribution system serving Rockland

County. This Project would allow United Water to increase the capacity of its water supply

system to meet the projected future demands for water in Rockland County, and therefore is

critical to United Water’s ability to continue to provide water for the County, including

providing adequate quantity, quality, and water pressure to meet the projected future demands

for County residents, businesses, and firefighting capabilities.

The Proposed Project would draw water through an intake structure located in Haverstraw Bay,

in the Hudson River, through an intake pumping station, to a water treatment plant. At the water

treatment plant, water would be treated to remove impurities and salinity, and chlorinated. The

potable water would be transmitted from the plant via new underground water transmission lines

that would connect to United Water’s existing water distribution network. The impurities and

salt removed from the water would be processed and disposed of in accordance with applicable

laws and regulations.

The Proposed Project would include the following elements:

! Water intake located in the Hudson River.

! Intake pumping station located on the Hudson River shoreline to draw water through the

intake.

! Water treatment plant where the water would be treated and disinfected.

! Piping for transmission of water between project elements, including piping for raw water

transmitted between the intake pumping station and the water treatment plant; piping to

transmit wastewater to the Haverstraw Joint Regional Sewage Treatment Plant (JRSTP); and

piping to convey potable water to the existing United Water distribution system.

! Potential upgrades to the JRSTP to increase the capacity of the plant’s outfall.

The Proposed Project is being designed to treat and deliver up to 7.5 mgd of potable water for

the exclusive use of United Water’s Rockland County customers. When the facility opens for

operation, it would treat and deliver less water, potentially 2.5 mgd to 5 mgd. As Rockland

County’s water demand increases, the Proposed Project would be expanded to meet that

demand, with the ultimate capacity at 7.5 mgd. Except where otherwise noted, this Draft

Environmental Impact Statement (DEIS) describes and evaluates the Proposed Project at its full

capacity of 7.5 mgd.

B. PROJECT LOCATION

The proposed Haverstraw Water Supply Project would be located in the Town of Haverstraw, in

Rockland County, New York, as shown in Figure 2-1. The buildings associated with the

Proposed Project would occupy two sites, referred to throughout this DEIS as the Intake Site and

the Water Treatment Plant Site. In addition to these two sites, the Proposed Project would also

have several other features that would occupy sites: the intake structure in the Hudson River, the

underground pipe for transmission of raw water from the Intake Site to the Water Treatment

Plant Site, and the underground pipes for conveying potable water from the treatment plant to

the existing United Water distribution mains. The various Project Sites are described below and

shown together on Figure 2-2. The facilities proposed for these sites are described later in this

chapter in section D, “Haverstraw Water Supply Project: Operations and Facilities.”

INTAKE SITE

The Intake Site consists of a one-acre portion of one tax parcel in the Town of Haverstraw,

21.09-2-1, located at 710 Beach Road. As shown in Figure 2-2, the Intake Site is on the south

side of Beach Road on a point of land that extends into the Hudson River. The Intake Site is

bounded to the north by the road and to the east by the Hudson River. To the west and south, it

abuts property used by the U.S. Gypsum Company (USG) in connection with its manufacturing

plant on the north side of Beach Road in the Town of Stony Point. An enclosed conveyor rises

from the Hudson River across the USG site that abuts the Intake Site, and crosses Beach Road.

The conveyor is used by USG to move supplies from barges that dock at a USG pier in the

Hudson River east of the site. Beyond the USG conveyor site, the Haverstraw Marina is south

and west of the Intake Site. The Intake Site is currently accessible via a driveway from Beach

Road through an adjacent portion of the USG property. A portion of the Site is used as a parking

area and by the adjacent Haverstraw Marina for the off-season storage of approximately 20

recreational boats. A small boathouse/fishing structure is also located just south of the Intake

Site. As described in section D, the Intake Site is proposed for development with an intake

pumping station to draw water from the Hudson River.

Chapter 2: Project Description

As discussed below in section D of this chapter, the water intake would extend from the

shoreline of the Intake Site approximately 1,000 to 1,200 feet into the Hudson River. The route

of the water intake pipe would extend approximately 500 feet beyond the grant line of the lands

under water granted to USG, into the public trust waters of the Hudson River.

WATER TREATMENT PLANT SITE

The Water Treatment Plant Site is a 9.03-acre site at 555-571 Beach Road in the Town of

Haverstraw (see Figure 2-3). The Water Treatment Plant Site consists of portions of four tax

parcels: 20.16-2-1, 20.16-2-2.1, 20.16-2-2.2, and 20.16-2-5. The Water Treatment Plant Site is

bounded to the east and southeast by the closed Haverstraw Landfill, to the west by a railroad

right-of-way owned by the CSX Corporation. Privately owned industrial properties are located

to the north and south of the Site. The JRSTP is located nearby, to the south of the Haverstraw

Landfill site. The Water Treatment Plant Site is a reclaimed area located within the boundary of

the now closed Haverstraw Landfill. The Site was not used for landfilling, but municipal waste

was historically stored there. This waste was removed during landfill closure and the Site was

excavated to provide soil to cap the adjacent landfill. Some fill material has recently been placed

on the Site. The Site is now vacant; about 1/3 of the Site is vegetated with a mix of grasses,

shrubs, and small trees and the rest is bare earth and a stormwater basin. The Site is substantially

lower in grade than the surrounding areas and is not accessible via roadways.

The Proposed Project also may incorporate a portion of an adjacent, vacant property to the south

of the Water Treatment Plant Site into the Site, for use as a staging area during construction (see

Chapter 15, “Construction Impacts”) or for potential easements or expansion. This property (also

shown in Figure 2-3) consists of one tax parcel, 20.16-2-6, and is 6.35 acres in size. The

property is owned by DSB Realty Associates, LLC and is referred to in this chapter as the DSB

property.

RAW WATER TRANSMISSION LINE ROUTE

The raw water transmission line route extends between the Intake Site and Water Treatment

Plant Site. As shown in Figure 2-2, the route follows the public right-of-way, running beneath

Beach Road and Ecology Lane to the JRSTP. Along Beach Road, the water line would cross

Minisceongo Creek either above-grade, alongside the bridge carrying Beach Road, or in a buried

pipe beneath the creek. At the JRSTP, it would continue westward along the south side of the

plant and beyond, finally bending northward to the Water Treatment Plant Site. The pipeline

route from the intake pumping station to the water treatment plant would be approximately 7,500

feet (1.4 miles) long. In addition, the route also passes through sections of USG property near

the Intake Site; the JRSTP; and the privately owned DSB property to the south of the Water

Treatment Plant Site.

POTABLE WATER MAIN ROUTES

At this time, potential routes have been identified but not finalized for the new potable water

main connections that would extend from the new water treatment plant (discussed in section D

later in this chapter). These potential routes are shown in Figure 2-4. As shown in the figure,

some of the potential routes extend westward from the Water Treatment Plant Site, crossing the

CSX railroad tracks and continuing along an east-west street to meet Route 9W. Others extend

south from the Water Treatment Plant Site, along North Wayne Avenue, Carol Street, or the

Haverstraw Water Supply Project DEIS

CSX access road adjacent to the railroad tracks, and then continue via Railroad Avenue either

westward to Route 9W or eastward to Tanneyanns Lane.

As discussed later in this chapter, it is also possible that some existing water mains would need

to be rehabilitated or replaced with larger mains. This may include an existing main beneath

Route 9W and a main beneath Filors Lane between Route 9W and Thiells Road. This

replacement and/or rehabilitation could be conducted as part of United Water’s regular water

main rehabilitation program.

C. HUDSON RIVER SOURCE WATER QUALITY

During the conceptual design phase for the Proposed Project, detailed information on water

quality in Haverstraw Bay and upstream and downstream along the river was collected to obtain

the current water quality characteristics. The data collected were used to refine the water

treatment processes to be best suited to the range of water quality conditions identified. This

section of the DEIS summarizes the water quality information collected, which the Proposed

Project will be designed to address. These data are also summarized in Chapter 9, “Natural

Resources,” and more detailed information is provided in Appendices 2.1, 2.2, and 2.3. In

addition, as described later in this section, hydrodynamic water quality modeling was conducted

to evaluate the potential effects of wastewater discharges to the river in the vicinity of the

proposed water intake.

WATER QUALITY SAMPLING RESULTS

The Hudson River is currently being used as a drinking water source by the City of

Poughkeepsie, the Town of Lloyd, the Village of Halfmoon, and the City of Latham. In addition,

it has also been used by the City of New York at Chelsea, NY during past drought emergencies.

Tables 2-1, 2-2, and 2-3 below compare a subset of water quality data collected in the vicinity of

the proposed location for the water intake for the Proposed Project with that of the other water

treatment plant withdrawals on the Hudson River. The tables also provide a comparison of

Hudson River water quality with data collected from the Delaware, Missouri, Mississippi, Ohio,

and Susquehanna Rivers, which are also used as sources of drinking water.

The data in the tables show that for many of the basic water quality parameters, the Hudson

River quality is similar to that of the other river supplies. One exception is the salinity of the

Hudson River, which is higher than that in the other rivers because of the tidal conditions south

of Poughkeepsie. For some parameters, the Hudson River exhibits better water quality than some

other major rivers that are used for drinking water supply. For example, sampling and analysis

were performed for Giardia and Cryptosporidium monthly from May 2007 to April 2008. A

total of 38 samples were collected from five sites within the vicinity of the proposed location of

the Haverstraw Water Supply Project’s new intake. With the exception of one sample that tested

positive for Giardia at the detection limit of 0.1 cyst/L, all other samples were below the

detection limit for Giardia and Cryptosporidium.

Potential issues for drinking water can include the presence of radionuclides, polychlorinated

biphenyls, and endocrine disrupting compounds/pharmaceuticals and personal care products. A

brief discussion of the monitoring results for each of these constituents is discussed below.

RADIOLOGICAL ANALYSIS

Due to the presence of the Indian Point nuclear power plant on the eastern shore of the Hudson

River in Buchanan, NY, some have expressed concern regarding the possible radiological

contamination of groundwater as well as the Hudson River close to the plant. A summary of the

radiological results from United Water’s sampling program is provided below. Table 2-4

summarizes the analyses performed for radionuclides in water samples collected at several

locations in the Hudson River in 2007 and 2008.

Table 2-4

Results of Radionuclide Sampling

Gross alpha 18 0-20 3.5 15 pCi/L

11 samples

Tritium 11 0-397 36 20,000 pCi/L3 Not detected in 10 out

of 11 samples

Notes: n = Number of samples 1 Not detected treated as 0. 2 MCL = Maximum contaminant level, the standard set by EPA for these radionuclides. MCLs are

calculated as the average of four quarterly samples. 3 Used as guidance when gross beta < 50 pCi/L.

Drinking water standards for radionuclides first require the determination of “gross alpha” and

“gross beta” measurements; these measurements are useful in providing an overall screening to

determine if further analysis of specific radionuclides is needed. Standards of the U.S.

Environmental Protection Agency (EPA) may be satisfied by testing for gross alpha and gross

beta radioactivity. The standards are considered to be met when the gross beta activity is lower

than or at the maximum contaminant level (MCL) set by EPA and concentrations of tritium and

strontium 90 are lower than or at the MCL. (MCLs for these radionuclides are calculated as the

average of four quarterly samples.) As shown in Table 2-4, both gross alpha and gross beta were

well below the EPA MCLs. Also, radium, uranium, strontium 90, and tritium were well below

their respective MCLs and /or guidance values.

POLYCHLORINATED BIPHENYLS (PCBS)

Polychlorinated biphenyls (PCBs) were commonly used in manufacturing processes until the

1970s, and were most commonly used in capacitors and transformers. They were also used for

hydraulic fluids, plasticizers, adhesives, fire retardants, dedusting agents, inks, lubricants, cutting

oils, in heat transfer systems, among other uses. However, PCBs have been classified by EPA as

a potential carcinogen and most uses of PCBs were banned by EPA in 1979. In the Upper

Hudson River, upstream of the Troy lock and dam near Albany, elevated levels of PCBs are

present in the river sediment.

2-9

Page 14: Chapter 2: Project Description A. INTRODUCTION

Haverstraw Water Supply Project DEIS

To address potential concerns related to PCBs in the Hudson River, the water quality sampling

program undertaken for the Proposed Project collected 17 samples that were tested for seven

different congeners of PCBs in 2007 and 2008 at five different locations in the Haverstraw-

Stony Point area during both high and low tidal cycles. All samples tested for PCBs exhibited

results that were found to be below detection limits for PCBs.

EPA’s February 2002 Record of Decision for the Hudson River PCBs Superfund Site addresses

the risks to people and ecological receptors associated with PCBs in the sediments of the Upper

Hudson River. Phase I dredging activities to remove PCB-contaminated sediment are expected

to start in 2009. 1 This remediation will be performed in accordance with performance standards

for resuspension during dredging that establish limits for concentrations of PCBs in river water

and downstream transport of PCBs. The standards include a primary standard of a not-to-exceed

river water PCB concentration and two action levels that trigger efforts to identify and correct

any cause of exceedance of the performance standards. The action levels are defined by far-field

(more than 1 mile downstream of dredging activities) and near-field (within approximately 1,000

feet of the dredging activities) criteria.

The Waterford Dam area is the southernmost area to be dredged for PCBs. Given the results of

the resuspension modeling for PCBs resulting from Phase 1 dredging, it is expected that PCB

levels will not exceed Control Level concentrations or the Primary Standard at one mile

downstream of the Waterford Dam area in Troy and at all points south for the entire duration of

dredging.2 PCBs resulting from the dredging would therefore not affect the Hudson River near

Haverstraw Bay, in light of the results from Phase 1 resuspension modeling, the use of

performance standards during dredging, and, most importantly, because Haverstraw Bay is more

than 100 miles from the area to be dredged and separated from that area by the Troy Dam.

ENDOCRINE DISRUPTING COMPOUNDS (EDCS) AND PHARMACEUTICALS AND

PERSONAL CARE PRODUCTS (PPCPS)

There are many compounds of emerging concern in both ground and surface waters. Compounds

of concern to health and environmental professionals, as well as the public, include endocrine

disrupting compounds (EDCs), and pharmaceuticals and personal care products (PPCPs).3 These

constituents are common to many water sources, and are not unique to the Hudson River.

The term “microconstituents” is frequently used to describe these compounds of concern.

Microconstituents have been defined by the Water Environment Foundation (WEF) as natural

and man-made substances, including elements and inorganic and organic chemicals detected

within water and the environment, for which continued assessment of the potential impact on

human health and the environment is a prudent course of action.

disrupting chemicals, estrogens, and other hormones; the acronym PPCPs is used to represent the

compounds listed as pharmaceutically active compounds, both positively and negatively charged, and

the fragrances.
