Opinion
Real party in interest Magma Energy, Inc. (hereafter Magma) applied to respondent Lake County Planning Commission (hereafter Planning Commission) for a use permit to drill three exploratory geothermal wells in an area on the slope of Mt. Konocti in Lake County. The Planning Commission ordered that a full environmental impact report (EIR) be prepared prior to approval of the permit. Magma filed an EIR, analyzing only the effects of the exploratory drilling. No consideration was given to the impact of a geothermal production unit in the event the exploratory wells were successful. The Planning Commission certified the EIR as being in compliance with the California Environmental Quality Act (hereafter CEQA), but denied Magma the use permit under section 78.2 of the Lake County Zoning Ordinance.
Magma appealed to respondent Lake County Board of Supervisors (hereafter Board of Supervisors) which overturned the Planning Commission decision and ordered that the Planning Commission issue a use permit for two of the exploratory wells. Appellant Lake County Energy Council filed in the superior court a petition for writ of mandate, seeking to set aside the certification of the EIR by the Planning Commission and *854 to require respondents Board of Supervisors and the Planning Commission to vacate and annul the use permit. The court entered judgment denying the writ and the Energy Council appeals.
The point in controversy is clear: Appellant asserts that in connection with an application for exploratory geothermal drilling, an EIR which is prepared must assess the effects of commercial development in the event that geothermal resources are encountered; Magma and respondents contend that such an EIR need only extend to the exploratory drilling for which the application is sought.
We commence our analysis by reference to the guidelines issued, by the Secretary of Resources for implementation of CEQA. (Cal. Admin. Code, tit. 14.) Section 15069 of these guidelines provides: “Where individual projects are, or a phased project is, to be undertaken and where the total undertaking comprises a project with significant environmental effect, the responsible agency or Lead Agency must prepare a single EIR for the ultimate project. Where an individual project is a necessary precedent for action on a larger project, or commits the Responsible Agency to a larger project, with significant environmental effect, an EIR must address itself to the scope of the larger project, subject to the limitation of Section 15066 of these Guidelines. Where one project is one of several similar projects of a public agency, but is not deemed a part of a larger undertaking or a larger project, the agency may prepare one EIR for all projects, or one for each project, but should in either case comment upon the combined effect.” (Italics added.)
Since exploratory drilling is no doubt a “necessary precedent” to the larger project of commercial development, the guidelines seem to require that the EIR address itself to the scope of the “larger project.” However, since the scope of the larger project is unknown until the initial project (exploratory wells) is completed, and the initial project, as will be shown below, does not “commit the Responsible Agency” to the larger project, it is arguable that an EIR need not encompass the contingency of commercial development.
The controversy is sharpened by California cases interpreting CEQA. While it is clear that tíre requirements of CEQA “cannot be avoided by chopping up proposed projects into bite-size pieces” which, when taken individually, may have no significant adverse effect on the environment

*856 In the instant case, a number of factors convince us that the scope of the inquiry in the subject EIR is not required by CEQA to include the effects of commercial geothermal production. In the first place, it must be recognized that without exploratory drillings, full-field geothermal development in the Mt. Konocti area remains a mere contingency. The drilling of these wells is necessary before Magma can at all assess whether or not the location should be considered suitable for development. At this point, no one knows whether the exploratory wells will uncover a reservoir of geothermal energy, whether the energy resource will consist of steam or hot water, whether that resource will prove of sufficient quality, quantity or temperature pressure so as to justify development, or how extensive such development will be. It therefore appears that at present Magma possesses no “reliable data to permit preparation of a meaningful and accurate report on the impact of commercial production” (No Oil, Inc., supra, at p. 77, fn. 5) other than the vaguest kind of generalities concerning geothermal production. Until the wells are drilled, no truly meaningful report could be prepared.
We note further that approval of the exploratory wells in no manner commits the Board of Supervisors to approval of general commercial development. In its findings pursuant to the granting of the use permit, the board states: “6. This use permit is for two (2) exploratory wells and the Board of Supervisors reaffirms that the granting of this use permit neither establishes precedent for geothermal field development in the immediate area, .nor includes commitment to single resource exploitation.” This case is thus clearly distinguishable from

Finally, we take cognizance of the fact that before any facilities for geothermal production are constructed, the state energy commission must evaluate and certify such facilities. (Pub. Resources Code, § 25500;
*857
The foregoing facts make clear that there is no danger that the county’s present approval of exploratory drilling will serve as a hindrance to future intelligent decision-making with respect to the environmental consequences of commercial geothermal development in the Mt. Konocti area. (See

The Supreme Court has indicated in

that an EIR dealing with exploratory drilling must discuss the impact of the commercial development which may result therefrom only where “meaningful inquiry” into the consequences of such development can be made. (
The judgment is affirmed.
