1. Description of Proposed Action
The proposed project consists of the occasional application of copper-based algaecides
at Lake Jennings Reservoir to control and prevent degradation of water quality resulting
from algae blooms. The application of algaecide will occur periodically, as needed to
address algae blooms, if Lake Jennings Reservoir is required to meet water supply
needs. The application of algaecide may require temporary exceedance of the
permitted levels of dissolved copper.
2. Schedule
The seasonal exemption would cover intermittent, periodic discharges that may occur
throughout the year. These discharges generally would be a single treatment and will
dissipate within approximately one week. The frequency of discharge, based on water
supply needs and occurrence or algae blooms, is not expected to be more than 2 times
annually.
3. Water Quality Monitoring Plan
Helix Water District will conduct water quality monitoring in accordance with our
approved Aquatic Pesticide Application Plan and the requirements of the Statewide
General National Pollutant Discharge Elimination System Permit for the Discharge of
Aquatic Pesticides for Aquatic Weed Control in Water of the United States General
Permit No. CAG990005 (Water Quality Order No. 2013-0002-DWQ (as amended by
Order No. 2014-0078-DWQ)).
4. CEQA Documentation
The required CEQA documentation is contained in the attachments. The Mitigated
Negative Declaration was publically noticed on the San Diego County Water Authority's
web site, within libraries in the surrounding community areas, and submitted to the
Office of Planning and Research State Clearinghouse. The MND was approved by the
Helix Water District Board on June 17, 2015 and the Notice of Determination was filed
with the County Clerk on June 22, 2015.
5. Contingency Plan
Lake Jennings Reservoir is a water source for Helix Water District's regional water
treatment plant which supplies the greater portion of eastern San Diego County in the
Helix service area and through neighboring water agency service areas. If an exception is
not granted, Helix Water District's ability to deliver a reliable water supply to its
customers and the neighboring agencies in the region would be impacted. The presence
of untreated algae blooms could result in significant taste and odor issues, impacting the
potential use as a supply. In the event that an exemption is not granted, Helix would be
required to rely on alternative supplies reducing reliability.

6. Identification of Alternative Water Supply
Helix Water District operates a regional treatment facility providing a safe and reliable
water supply to its service area and neighboring agencies in the region. Helix Water
District can receive water from multiple sources to supply the treatment facility. In the
event of an algal bloom in Lake Jennings Reservoir, Helix Water District would switch to
an alternative source to meet supply needs. Normally, Helix Water District would allow
an algal bloom in Lake Jennings Reservoir to run its natural course without applying
algaecide. In the event that alternative sources were not available to fully meet the
demand, not having the ability to effectively manage water quality in Lake Jennings
Reservoir could result in potential water supply shortage.
7. Residual Waste Disposal Plans
Helix Water District operations is not expected to result in a measurable amount of spill
or residual waste. Any normal operational spill would only contain a small amount of
algaecide which is not significant enough to impact the beneficial use of the reservoir
and its surrounding watershed. In the event of a larger spill, Helix Water District would
contain, cleanup and dispose of spilled algaecide following the District's Hazardous
Materials BusinessP lan and MSDS protocols. Residual waste will be handled according
to product label instructions and applicable regulations.
