TTP Scoping Comments


Important Update:

WAPA pulls out of the TTP.  See more here.

Western is cancelling the preparation of the environmental impact statement for the proposed Transmission Agency of Northern California Transmission Project. TANC has announced that it cannot undertake a detailed environmental analysis of the proposed project that would have involved new and upgraded 230-kV and 500-kV transmission lines, substations and related facilities in northern California.”

Instructions for Writing Comments

Remember, this is the stage in the entire process where our impact is the greatest. Choose an issue(s) that is meaningful to you -- one that you can write about with authority and passion.  If it can be unique, so much the better.  One of the main purposes of the CEQA/NEPA process is to get input that can be known only at the local level; things you know about that the designers of the project didn’t know when they designed it; things that could conceivably make the project better, different or, in some cases, even nonexistent.

The “No project” option -- whether the TTP should be built at all must and will be considered.  Comments about the overall logic behind the project, it's practicality, it's financial viability, etc. are legitimate.

It is important to identify concerns but also important to provide alternatives or mitigation measures wherever possible. By law, any comment that is submitted must be addressed.

What Should Be Included in a Comment?

You can include several issues on the same comment form, letter or email.  If you choose to do this, use some sort of outline format so that one can clearly identify each point or topic. Use e.g. capitals and underlining. 

Consider starting from TANC's own list of points. Do not feel you must limit yourself to those! They are listed on the WAPA website under the name Scoping Issues Handout in the Scoping Meeting Materials section.  The  URL is:


Sometimes it helps to make a list of questions to either pose or to focus on for generating your own comments:


If you would like to use an official comment form for your comment, you can download one from the WAPA website.

You should keep a record of the letter such as mailing a copy to yourself or keeping a copy on your computer. Then, when the draft EIR comes out, you can see if your comment was addressed and, if it wasn't, you can call them on it.  If you feel that TANC might ignore your letter, then send it certified, registered, or return receipt request.

It's ok to send the comments via email to - use the receipt feature of your email program if it has one, send a copy to yourself, and print out a copy for your files.  You can also send a hard copy of the same comments via mail postmarked before July 30th.  (Note Extension)

Delivering Your Comments

Only written comments will be accepted and they should be mailed to:

  1. Is this project needed?
    If not, why don't you think it is justified?
    Use their own data where possible and outside data as obtained.

  2. Is it safe?
    Health concerns, fire concerns, water concerns, roads and dust.

  3. Who pays for it?

  4. Who benefits?

  5. Why was this route selected?
    (And arguments for why it shouldn't be considered.)

  6. Are there better alternatives to creating new power corridors?
    Solar homes, the plan for net zero energy homes to be built in CA starting 2020 reducing demand.

  7. What are the environmental impacts likely to result from this proposal?

  8. Do the known risks outweigh the proposed benefits?

There has been lots of discussion on a Google Group that has been set up to exchange ideas and concerns about the TTP.  To access this, you have to join the Google Group. It is easy to do.

Existing Routes:

Note that the government requires first consideration be given to existing routes:

  1. 1.Designation of Transmission Corridor Zones

  2. 2.Proposed Section 368 Energy Corridors

Do we really need more transmission lines?

“Thus, integrating and coordinating energy efficiency and distributed generation programs is essential to allow customers to gain the largest benefit from their expenditures...

...Other forms of distributed generation, even if not renewable, can also have benefits over centrally located generation that suffers from transmission and distribution line losses. Distributed generation can also help support grid reliability.”

Glossary of Important Terms
TANC and WAPA: The Transmission Agency of Northern California (TANC) is a CA Joint Powers Agency and the Western Area Power Administration (WAPA) is part of the US Department of Energy.  Both engage in the financing, construction and administration of high voltage electric transmission lines.
TTP: The TANC Transmission Project (TTP) is a major electrical transmission project that will result in the construction of about 600 miles of 230-kV and 500-kV electric transmission lines and a number of electrical substations.  If built, it will extend from Lassen County to the S. Bay, San Joaquin County and the Sierra foothills.
CEQA/NEPA and EIR/EIRS: In the case of the TTP, the two reports are produced by one joint process, called CEQA/NEPA and will produce a single report, called the EIR/EIS. California Environmental Quality Act (CEQA) is a CA state law that requires the creation of an Environmental Impact Report (EIR).  National Environmental Protection Act (NEPA) is a federal law that requires the creation of an Environmental Impact Statement (EIS).
Scoping:  Scoping is the process by which the range or scope of the EIR/EIS is determined or, stated differently, the process of deciding what must be included in the EIR/EIS.
