Federal Register / Vol. 89, No. 224 / Wednesday, November 20, 2024 / Notices 91739 

Drought Adder Component: A 

formula-based revenue requirement that 

includes future purchase power above 

timing purchases, previous purchase 

power drought deficits, and interest on 

the purchase power drought deficits. 

The second step revenue requirement is 

subject to change during the annual 

Drought Adder adjustment processes 

starting in January 2026. 

Annual Drought Adder Adjustment 

Process 

The Drought Adder may be adjusted 

annually using the above formulas for 

any costs attributed to drought of less 

than or equal to the equivalent of 2 

mills/kWh to the Power Repayment 

Study (PRS) composite rate. Any 

planned incremental upward 

adjustment to the Drought Adder greater 

than the equivalent of 2 mills/kWh to 

the PRS composite rate will require a 

public process. 

The annual review process is initiated 

in early summer when WAPA reviews 

the Drought Adder component and 

provides notice of any estimated change 

to the Drought Adder component charge 

under the formula. In October, WAPA 

will make a final determination of any 

change to the Drought Adder 

component charge, either incremental or 

decremental. If a Drought Adder 

component change is required, a 

modified Drought Adder revenue 

requirement and the associated charges 

will become effective the following 

January 1 and will be identified in a 

Drought Adder modification update. 

WAPA will inform customers of updates 

by letter and post updates to WAPA’s 

external website. 

Billing Demand 

The billing demand will be the greater 

of (1) the highest 30-minute integrated 

demand measured during the month up 

to, but not in excess of, the delivery 

obligation under the power sales 

contract, or (2) the contract rate of 

delivery. 

Adjustments 

For Billing for Unauthorized 

Overruns: For each billing period in 

which there is a contract violation 

involving an unauthorized overrun of 

the contractual obligation for peaking 

demand and/or energy, such overrun 

shall be billed at 10 times the above 

rate.

Notice of Availability of Final 

Designation of Certain Stormwater 

Discharges Within Two Watersheds in 

Los Angeles County, California Under 

the National Pollutant Discharge 

Elimination System of the Clean Water 

Act 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice of availability. 

SUMMARY: The Regional Administrator 

of the Environmental Protection Agency 

(EPA) Region 9 is providing notice of 

the availability of EPA’s Final 

Designation of stormwater discharges 

from certain commercial, industrial and 

institutional (CII) sites in the Alamitos 

Bay/Los Cerritos Channel Watershed 

and the Dominguez Channel and Los 

Angeles/Long Beach Inner Harbor 

Watershed in Los Angeles County, 

California for National Pollutant 

Discharge Elimination System (NPDES) 

permitting under the Clean Water Act 

(CWA). 

DATES: EPA’s Final Designation of 

Stormwater Discharges from Certain 

Commercial, Industrial and Institutional 

Sites in the Alamitos Bay/Los Cerritos 

Channel Watershed and the Dominguez 

Channel and Los Angeles/Long Beach 

Inner Harbor Watershed in Los Angeles 

County (‘‘EPA’s Final Designation’’) was 

signed on November 5, 2024. 

FOR FURTHER INFORMATION CONTACT: 

Eugene Bromley, EPA Region 9, Water 

Division, NPDES Permits Section 

(WTR–2–3), 75 Hawthorne Street, San 

Francisco, CA 94105; telephone (415)

epa.gov, or R9RDA@epa.gov. 

SUPPLEMENTARY INFORMATION: 

A. Does this action apply to me? 

Entities potentially regulated by this 

action include a wide variety of 

privately-owned CII facilities such as 

shopping centers, office complexes, 

warehouses, private schools and 

hospitals, and various manufacturing 

facilities. Entities affected by this action 

are located within either of two 

watersheds in Los Angeles County, in 

California: the Los Cerritos Channel/ 

Alamitos Bay Watershed or the 

Dominguez Channel and Los Angeles/ 

Long Beach Inner Harbor Watershed. 

This description of affected entities is 

not intended to be exhaustive, but rather 

provides a guide for readers regarding 

entities likely to be affected by this 

action. This description of affected 

activities includes the types of entities 

that EPA is now aware could potentially 

be affected by this action. Other types of 

entities not included could also be 

affected. To determine whether your 

entity is affected by this action, you 

should also review the description of 

EPA’s action in documents online at the 

website listed in the section C below. If 

you have questions regarding the 

applicability of this action to a 

particular entity, consult the person 

listed in the FOR FURTHER INFORMATION

CONTACT section. 

B. Summary of Final Designation 

In the Final Designation, EPA has 

determined that stormwater discharges 

from certain CII sites in the Los Cerritos 

Channel/Alamitos Bay and Dominguez 

Channel and Los Angeles/Long Beach 

Inner Harbor Watersheds in Los Angeles 

County are contributing to violations of 

water quality standards and require 

NPDES permit coverage under the CWA. 

The Final Designation differs from the 

Revised Preliminary Designation of 

November 2, 2023 (88 FR 75282) in that 

EPA is not designating privatelyoperated facilities at the Ports of Long 

Beach and Los Angeles at this time. EPA 

is taking a phased approach to this Final 

Designation such that EPA may consider 

designating stormwater discharges from 

additional CII sources in the future. 

This Final Designation is in response 

to two September 15, 2015 petitions 

entitled ‘‘Petition For A Determination 

That Stormwater Discharges From 

Commercial, Industrial, And 

Institutional Sites Contribute To Water 

Quality Standards Violations in 

Dominguez Channel and the Los 

Angeles/Long Beach Inner Harbor (Los 

Angeles County, California) and Require 

Clean Water Act Permits,’’ and ‘‘Petition 

For A Determination That Stormwater 

Discharges From Commercial, 

Industrial, And Institutional Sites 

Contribute To Water Quality Standards 

Violations in the Alamitos Bay/Los 

Cerritos Watershed (Los Angeles 

County, California) And Require Clean 

Water Act Permits’’ as well as an order 

from the U.S. District Court for the 

Central District of California in Los 

Angeles Waterkeeper v. Pruitt, 320 F. 

Supp.3d 1115 (C.D. CA 2018). 

EPA’s Final Designation is made 

pursuant to CWA sections 402(p)(2)(E) 

and (6) and EPA’s implementing 

regulations at 40 CFR 122.26(a)(1)(v) 

and 40 CFR 122.26(a)(9)(i)(D) that 

authorize EPA to designate stormwater 

discharges for regulation under the 

NPDES permitting program that are 

contributing to violations of water 

quality standards but are not otherwise
