Appendix 1
I. INTRODUCTION
The stated purpose of this proceeding ((R) 07-12-001) is to determine whether the Commission should adopt the proposed revisions to General Order (GO) 95 as submitted by the GO 95/128 Rules Committee in Petition (P) 07-07-020.
II. PROCEDURAL HISTORY
In Decision (D) 07-02-030, the Commission adopted new GO 95 rules for the installation of wireless antennas on jointly used utility poles, but expressly reserved for a later date the possible adoption of rules for the installation of wireless antennas above or between supply lines.
Subsequently, the GO 95/128 Rules Committee submitted P.07-07-020, recommending revisions to Rule 94 as adopted in D.07-02-030 and proposed changes to other GO 95 rules to establish new uniform construction standards for wireless antennas installed above or between supply conductors operating at 0 -50,000 Volts, including pole-top antennas above communication lines on joint-use utility poles.
The Commission later issued an Order Instituting Rulemaking (OIR) 07-12-001 to consider uniform construction standards for "pole-top antennas." Opening and reply comments were filed on January 14 and February 15, 2008, respectively. A prehearing conference (PHC) was held on March 5, 2008 to develop a joint PHC statement that affirmed the Parties' consensus on the scope and schedule of this instant proceeding.
On March 21, 2008, the Commission issued a Scoping Memo setting forth the scope, schedule, category, need for hearing, the presiding officer and the rules for ex parte communications in this instant proceeding, pursuant to Rule 7.3(a) of the Rules of Practice and Procedure.
III. WORKSHOPS
In keeping with the workshop calendar established in the Scoping Memo, a two-day technical workshop was convened in San Francisco on April 03-04, 2008, followed by a one-day workshop in San Diego on April 16, 2008 and concluded with a one-half day workshop in San Francisco on May 01, 2008.
San Francisco Workshop
On April 3, 2008, interested parties met to consider several audio-visual presentations in advance of engaging in technical discussions concerning the minimum vertical clearances between wireless antennas and supply lines operating at 750 - 22,500 Volts noted in Proposed Rule Change (PRC) #4 (Rule 38, Table 2, new Case 21). After the lunch break, the CPSD representative stated that after an internal review, the CPSD was officially withdrawing a previously stated concern regarding the possible need for insulating a pole-top antenna's communication cables that pass high voltage supply lines. At the conclusion of the afternoon session, attendees agreed to reconvene the next morning to discuss, in more detail, the possible reduction of the 96-inch vertical clearance (in PRC #4) to 72-inches.
During the April 4th morning session, attendees thoroughly assessed the correlating provisions of Case 21 and Rule 94 and agreed that each entity would need to consider (internally) the ramifications of a 72-inch vertical clearance in advance of the next workshop. A draft "red-line" revision of new Case 21, including a 72-inch minimum vertical clearance between antennas (including associated equipment and support elements) installed above 750 - 35,000 Volt supply lines was prepared. During the afternoon session, attending parties also agreed to consider certain editorial revisions to Rule 94 (PRC #1), Rule 91.3-B (PRC #2) and Rule 92.1-F2 (PRC #3). Before adjourning, Raymond Fugere (CPSD) offered to revise the Figures 94.1 - 94.5 and Sam Stonerock (SCE) offered to organize the proposed workshop revisions to PRCs 1-4. Both the Figures and revisions were subsequently distributed to the Parties.
San Diego Workshop
On April 16th, interested parties met at the San Diego Sheraton Hotel. At the start of the workshop, a non-binding poll indicated attending parties either agreed with the previously proposed 72-inch clearance or chose to take no position.
During the morning session, no "showstoppers" were identified; however, attendees did engage in a protracted discussion about the implications of a 72-inch vertical clearance. Because there appeared to be some interpretive ambiguity stemming from Footnote "v v" to Case 21, the attendees eventually agreed to revise this footnote.
During the afternoon session, attendees discussed revisions to Figures 94.1 - 94.5 and concluded that a new Figure that encapsulates the variety of wireless antenna installations above and below supply and communication lines on a joint-use utility pole would be preferable to five separate Figures.
Prior to adjournment, the remaining attendees agreed to reconvene via teleconference on April 24th, at 8:30 a.m., to review the draft workshop report and identify new items of concern (if any) in advance of a scheduled teleconference with ALJ Kenney on April 25. Raymond Fugere offered to continue development of a new Figure (94-1) and Sam Stonerock agreed to compile and compose a draft workshop report for distribution to parties on or before April 21.
San Francisco Workshop
On May 01, 2008, interested parties met at the California Public Utilities Commission offices in San Francisco to resolve an interpretive dispute arising after the San Diego Workshop. The attendees20 discussed the possible addition of a new footnote "yy" to apply to Columns E, F, and G of new Case 21, that would allow certain support elements (for example, pole-top antenna mounting brackets) to extend into the required vertical clearance by "mutual agreement." After extensive discussion, the attendees21 concluded the new footnote was unnecessary because existing GO 95 Rule 15.2 allows experimental installations 15 days after the filing of a full statement with the Commission disclosing such installation, provided the appropriate precautions and other requirements of Rule 15.2 are met.
IV. CONCLUSION
Before the first technical workshop was convened, Parties agreed that the 8-foot vertical clearance expressed in Rule 38, Table 2, Case 21 Columns E, F, G was the principal matter of dispute. Parties also agreed that a number of editorial revisions should be considered in light of the written comments.
After three and one-half days of careful review and discussion during technical workshops sessions (including several parties' technical presentations) and multiple hours expended between workshops, it was determined that a 6-foot vertical clearance between Antennas (including associated equipment and support elements) and supply lines energized at 750 - 35,000 Volts is an appropriate minimum requirement.
It was also determined that additional practical and editorial revisions to Rules 94, 91.3, 92.1, and Rule 38, Case 21 are needed to help ensure the new "pole-top" antenna requirements: (1) protect the safety of utility workers and the public; (2) do not compromise system reliability; (3) are consistent with other GO 95 rules; and (4) meet the Commission's broader goal of facilitating the expansion of California's wireless infrastructure.

Rationales for GO 95 Rules
Developed in R.07-12-001 Workshops
Introduction
Many of the proposed revisions to Proposed Rule Changes (PRCs) 1-4 developed during the technical workshops stemmed from the central topic of dispute (i.e., "vertical clearances"), while other revisions are more editorial in nature and intended to clarify conditions and/or help ensure continuity within the rule itself or the within the context of other General Order (GO) 95 requirements.
The rationales provided herein are not intended for use as "rule interpretations," but should be viewed as a high-level account of the decisions reached by the Parties attending the workshops.
Final Version - PRC #1
94.3-B: This revision is linked to new 94.3-C and demonstrates the differences between "associated elements" and "support elements".
New 94.3-C: This revision would add a new Subsection "C" and encapsulate the intent of the deleted Section 94.4 (proposed by the Rules Committee). This revision demonstrates the differences between "support elements" and "associated elements," and sets pole-top extensions apart from both categories.
The fine print note is needed to ensure that the material strengths and safety factors of support elements and pole-top extensions meet the requirements as those for Supply utilities constructing at the top of a joint-use utility pole.
New 94.4: In addition to being renumbered from (original) 94.5, several formatting and editorial corrections were made to Subsections A, B, E, F and G, due in part to the recommendations made by the CPSD and PG&E.
Also, the references to multiple Figures (94.1 - 94.5) were replaced with references to a new composite Figure 94.1.
New 94.5: Renumbered from (original) 94.6.
New 94.6: Renumbered from (original) 94.7, a reference to (original) Figure 94.3 was also removed as parties agreed this reference was no longer needed.
New 94.7: Renumbered from (original) 94.8. The text -"Exception to" was deleted as parties agreed the entirety of Rule 91.3 should be referenced.
New 94.8: Renumbered from (original) 94.9. Subsections A, A(1), B and C were modified to address PG&E and CPSD comments and to clarify the proper application of these requirements
The revisions to Subsection B(2) were made in conjunction with the revisions to PRC #4 to clarify that a wireless antenna's communication cables and conductors must be encased by suitable protective covering within the ascribed 6 ft. vertical clearance between wireless antennas and 750 - 35,000 Volt supply lines.
The revision to Subsection B(3) was made to reconcile the revised voltage ranges now expressed in B(2).
The revisions to Subsection B(3) were made to reconcile the text with the revisions to Subsection A.
New 94.9: Renumbered from (original) 94.10.
Final Version - PRC #2
91.3-B, Exception: This revision was made in response to a CPSD comment regarding the use of the term "designated space" and still allows for the omission of pole steps when a wireless antenna is installed between or above supply lines.
Final Version - PRC #3
92.1-F(2): The revision to the final paragraph reconciles the editorial revisions proposed in Rule 94 and adds a reference to same.
Final Version - PRC #4
Columns A - D and H: No changes were made to the vertical clearances originally expressed in PRC #4. The principle revisions involve the Footnote designations.
Columns E - G: These revisions specify that a minimum 6 ft. vertical clearance is required between wireless antennas installed above supply lines operating at 750 - 35,000 Volts. Notably, the Footnote designations have been removed as there are no allowable vertical clearance reductions for these voltage ranges.
Footnotes:
New "tt" - text revised to match Rule 94 Exception.
New "uu" - Revised text from (original) "xx". Renumbered to support alphabetical rearrangement of Footnotes within the Case. An editorial revision was also made to the cited rules.
New "vv" - revised from (original) "ww" for editorial purposes. New text encompasses previously referenced lead-in wires, drip loops and incidental wiring into new term "associated cables". This footnote retains the original option of reducing the expressed vertical clearance for these cables by 12 inches.
New "ww" - revised from (original) "uu" for editorial purposes. Editorial change clarifies the excepted vertical clearance is applicable to cables installed by Antenna's owner/operator.
New "xx" - allows for a reduction in the prescribed vertical clearance under a specific set of circumstances.
New "yy" - revised from (original) "vv" for editorial purposes. No changes to text.
Original "zz" - deleted, as workshop attendees agreed to clearances for Columns E - G.
