NAC704.772. Description of operating system.

The detailed description of the proposed operating system must include:

     1. An explanation of the type of system to be used, including:

     (a) The number, size, depth and productive capacity of the wells and pumps;

     (b) The amount, type and size of the pipelines for transmission and distribution;

     (c) The type of system for heat exchange, together with supporting test data;

     (d) The type of system for injection or water disposal system which will be incorporated into the system;

     (e) The type of facility for water treatment, if any;

     (f) The type of metering system, if any; and

     (g) The type of backup or standby facilities, if any, which the applicant will provide or will require individual customers to provide.

A map in sufficient detail to show the location of the facilities for production, transmission and distribution, including the wells, pumps, pipelines, heat exchangers, and other components, and their spacing from the service lines of other utilities. This map must be of the same size as the map submitted with the application for water rights.

     3. A list of all other utilities whose underground systems may be affected by the proposed system, a description of the manner in which each of those systems may be affected, and an explanation of the safety measures which the applicant will take to ensure that those systems will not be adversely affected.

     4. A statement showing:

     (a) The base and peak loads which the geothermal system is capable of supplying; and

     (b) The applicant’s projections of the base and peak loads which will be supplied during the 1st, 5th and 10th years of operation,

Ê with his or her supporting calculations based on pumping tests and test data on the efficiency of the heat exchangers in terms of British thermal units per hour of output under standard conditions.

     5. A statement signed by a licensed professional engineer or by an official having responsibility to enforce the local building code, that:

     (a) The calculations of the load and design of the system have been reviewed;

     (b) The calculations of the load appear reasonable; and

     (c) The system is designed in compliance with the applicable codes and has sufficient capacity to meet the projected uses.
