Notice of Intent to Prepare a Supplemental Environmental Impact
Statement for Milcon Project P-527b, Sewage Effluent Compliance, at
Marine Corps Base Camp Pendleton, California
AGENCY: Department of the Navy, DOD.
ACTION: Notice.
-----------------------------------------------------------------------
SUMMARY: The U.S. Marine Corps announces its intent to prepare a
Supplemental Environmental Impact Statement (EIS) to evaluate the
environmental effects of proposed alternative methods of sewage
effluent disposal, in order to achieve compliance with a San Diego
Regional Water Quality Control Board (RWQCB) Cease and Desist Order at
Marine Corps Base (MCB), Camp Pendleton. This report will supplement
the Sewage Effluent Compliance Project, Lower Santa Margarita Basin
Environmental Impact Statement/Report (EIS/R).
DATES: Submit comments on or before March 23, 1998.
ADDRESSES: Send written comments to Southwest Division, Naval
Facilities Engineering Command, 1220 Pacific Highway, San Diego, CA
92132-5190, (Attn: Ms. Vicky Taylor, Code 533.VT
FOR FURTHER INFORMATION CONTACT: Ms. Vicky Taylor, (619) 532-3007.
SUPPLEMENTARY INFORMATION: Pursuant to section 102(2)(C) of the
National Environmental Policy Act (NEPA) of 1969 as implemented by the
Council on Environmental Quality Regulations (40 CFR parts 1500-1508),
the U.S. Marine Corps announces its intent to prepare a Supplemental
Environmental Impact Statement (EIS) to evaluate the environmental
effects of proposed alternative methods of sewage effluent disposal, in
order to achieve compliance with a San Diego Regional Water Quality
Control Board (RWQCB) Cease and Desist Order at Marine Corps Base
(MCB), Camp Pendleton. The Sewage Effluent Compliance Project, Lower
Santa Margarita Basin Environmental Impact Statement/Report (EIS/R),
which this report will supplement, addressed a system of pumps and
piping to deliver effluent from Sewage Treatment Plants 1, 2, 3, 8, and
13 to percolation ponds and an existing ocean outfall for discharge.
Each of the three alternatives evaluated included an element of
effluent or brine discharge through the ocean outfall. During final
consideration of the proposed action, the City of Oceanside City
Council disapproved use
[[Page 5791]]
of its ocean outfall, thus requiring evaluation of further
alternatives.
MCB Camp Pendleton is proceeding with on-base construction of the
effluent collection and percolation pond elements of the disposal
system described in the Final EIS/R and Record of Decision. This
Supplemental EIS will analyze four alternatives to provide additional
and sufficient disposal capacity, without the use of an ocean outfall,
to achieve compliance with the San Diego RWQCB Cease and Desist Order.
The four alternatives include: Alternative 1, land disposal--
percolation of all effluent; Alternative 2, land and live stream
disposal--percolation with seasonal discharge; Alternative 3, land and
live stream disposal--percolation, advanced treatment and live stream
discharge; and Alternative 4, land disposal--percolation, advanced
treatment and reclamation. All alternatives will require the
construction of percolation ponds at up to three locations; Lemon
Grove, I-5/Railroad site, and the Boat Basin site. Under Alternative 1,
the effluent would be conveyed through underground piping between the
three sites. Most of this piping would be installed in existing
roadways.
Under Alternative 2, berm height and depth at Lemon Grove will be
increased, and an effluent storage pond will be constructed at Stuart
Mesa. These structures will accommodate effluent storage when effluent
input to the percolation ponds exceeds the percolation rate, and live
stream disposal is not feasible. The effluent will be discharged from
the Lemon Grove and Stuart Mesa storage ponds to the Santa Margarita
River when the volume of river flow provides sufficient dilution of the
effluent. The proposed discharge point will be north of the Lemon Grove
ponds.
Alternative 3 will process effluent, that is in excess of the
percolation rate, to remove nitrogen, phosphorous and other
constituents, and will be discharged to the Santa Margarita River at
the same point identified in Alternative 2. Construction of an advanced
water treatment (AWT) facilities adjacent to Sewage Treatment Plant
(STP) 13 and some effluent storage capacity will be required. Although
the AWT would improve the quality of the effluent, it is not
anticipated that the current Basin Plan objectives for total dissolved
solids (TDS) would be achieved, and modification to the Basin Plan
would be required.
Alternative 4 will be similar to Alternative 3, except the AWT
effluent will be conveyed to a point near the existing irrigation
system and used for irrigation of on-base, leased agricultural lands
northwest of the Lemon Grove ponds, on the east and west sides of I-5.
In addition, an alternative for a more limited expansion of the
Lemon Grove Ponds will be considered in the Supplemental EIS. This
alternative would limit the size of the Lemon Grove pond expansion to
avoid the removal of approximately 300 eucalyptus trees. This
alternative may be combined with any of Alternatives 1-4.
A supplement to the previously issued EIR is not required since the
revised proposed action does not require local approvals or California
Environmental Quality Act certification.
The scope of the analyses and issues of concern for this
Supplemental EIS are anticipated to be very similar to those addressed
in the Final EIS/R. The major issues are expected to be hydrology and
water quality, biological resources, and cultural resources. Other
issues to be addressed include geology and soils, air quality, land
use, transportation and circulation, noise, visual resources, safety
and environmental health, utilities, socioeconomics, and environmental
justice.
This notice has been mailed to all parties who commented on the
Sewage Effluent Compliance Project, Lower Santa Margarita Basin
Environmental Impact Statement/Report (EIS/R), and other interested
parties. This Notice has also been published in local newspapers. The
Marine Corps invites agencies, organizations, and the general public to
provide written comments relative to the proposed project and the
issues to be addressed in the Supplemental EIS. Scoping comments should
clearly describe specific issues or topics which the commentor believes
the Supplemental EIS should address. Written statements or questions
regarding the scoping process should be received no later than March
23, 1998, and should be sent to: Southwest Division, Naval Facilities
Engineering Command, 1220 Pacific Highway, San Diego, CA 92132-5190,
(Attn: Ms. Vicky Taylor, Code 533.VT), phone (619) 532-3007.
Dated: January 30, 1998.

Colonel, USMC, Acting Head, Land Use and Military Construction Branch,
Facilities and Services Division, Installations and Logistics
Department, By direction of the Commandant of the Marine Corps.
