5. Contributions of Other Parties

Section 1801.3(f) requires an intervenor to avoid participation that duplicates that of similar interests otherwise adequately represented by another party, or participation unnecessary for a fair determination of the proceeding. Section 1802.5, however, allows an intervenor to be eligible for full compensation where its participation materially supplements, complements, or contributes to the presentation of another party if that participation makes a substantial contribution to the Commission order.

Sarvey alleges that his approach was unique and did not duplicate the efforts of other parties because he took a risk-based approach and utilized the Tracy Youth Sports Park EIR, the City of Tracy's General Plan, plus over 3,000 pages of documents received in discovery to establish his position in mediation. We affirm that Sarvey's work did not duplicate the efforts of other intervenors.

After we have determined the scope of a customer's substantial contribution, we then look at whether the amount of the compensation request is reasonable.
