the Clean Water Act

Elimination System (NPDES) permitting program. This action, if

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 Dominquez Channel/Los Angeles/

B. Summary of Preliminary Designation

    CWA section 402(p)(2)(E) and (6) and EPA's implementing regulations 
at 40 CFR 122.26(a)(9)(i) authorize EPA to designate stormwater 
discharges for regulation under the NPDES permitting program. Those 
provisions authorize the Agency to regulate stormwater discharges that 
contribute to a water quality standard violation or that are a 
significant contributor of pollutants to waters of the United States, 
or where controls are needed based on wasteload allocations that are 
part of total maximum daily loads. This authority is often referred to 
as ``residual designation authority'' or RDA. EPA is providing notice 
of and soliciting comment on its preliminary designation for NPDES 
permitting of unregulated stormwater discharges from certain 
commercial, industrial and institutional (CII) facilities in the Los 
Cerritos Channel/Alamitos Bay and Dominquez Channel/Los Angeles/Long 
Beach Harbor Watersheds in Los Angeles County, including privately 
operated CII facilities at the Ports of Long Beach and Los Angeles. EPA 
is also taking comment on whether privately operated CII facilities at 
municipal airports located within the watersheds should be included.
    This preliminary designation is in response to a 2018 District 
Court order in Los Angeles Waterkeeper v. Pruitt, as well as 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.''

C. How can I submit comments?

    Submit comments by the deadline identified in this Federal Register 
notice. Information on how to submit comments and documents related to

    Once submitted, comments cannot be edited or removed from the 
administrative record. The EPA may publish any comment received as part 
of documentation (e.g., response to comments document) associated with 
its final decision. Do not submit in your comment any information you 
consider to be Confidential Business Information (CBI), Proprietary 
Business Information (PBI), or other information whose disclosure is 
restricted by statute. Multimedia submissions (audio, video,

etc.) must be accompanied by a written comment. The written comment is 
considered the official comment and should include discussion of all 
points you wish to make. The EPA will generally not consider comments 
or comment contents located outside of the primary submission (i.e., on 
the web, cloud, or other file sharing system).
