1. Authority
EXHIBIT 1
MEMORANDUM OF UNDERSTANDING BETWEEN THE
UNITED STATES FOREST SERVICE, DEPARTMENT 66-06-58-01
OF AGRICULTURE, AND THE NATIONAL WEATHER
SERVICE, DEPARTMENT OF COMMERCE
WHEREAS, the National Weather Service desires to install weather data-gathering equipment for purposes other than fire weather forecasting in certain National
Forest areas within Region 6 of the Forest Service; and
WHEREAS, the United States Forest Service desires to make available to the
National Weather Service the use of National Forest lands for this purpose;
NOW, THEREFORE, the United States Forest Service, herein referred to as the
Forest Service, acting by and through the Regional Forester, Region 6; Portland,
Oregon, and the National Weather Service, herein referred to as the Weather
Service, acting by and through the Regional Director, Salt Lake City, Utah, agree as follows:
A. THE FOREST SERVICE WILL:
1. Grant permission, subject to existing laws, regulations and all valid existing claims, to the Weather Service for the use of lands in the
National Forests within Region 6 for the purpose of locating, installing, operating and maintaining weather and/or streamflow data-gathering equipment. Each site authorized under this Memorandum of
Understanding will, in addition, be covered by a standardized supplement describing the specific National Forest location and outlining any other specific conditions relating to the occupancy and use of the particular site (a sample is included as Exhibit A to this
Memorandum or Understanding).
2. Instruct the Forest Supervisors of the National Forests to cooperate fully with the Weather Service in all matters relating to the use and administration of National Forests for the purposes stated in A-1 above.
3. Whenever possible and feasible, encourage the District Rangers who maintain Weather Service climatic substations to continue their

R-6 SUPPLEMENT 1500-91-2 1532-1532.2
EFFECTIVE 1/2/91 Page 3 of 9 weather observation programs on a daily basis, seven days per week, year-round.
4. Notify the Weather Service well in advance when unavoidable circumstances will require moving the weather data-gathering equipment. Changes in management or use of an instrument site which would impair its value for weather data collection will not be made unless there is no other reasonable alternative. Compatible uses of the site will be continued.
B. THE WEATHER SERVICE WILL:
1. Prior to use and occupancy of National Forest lands, notify the appropriate Forest Supervisor by application letter of its plans and obtain Forest Service review and approval of location and construction plans; and take up directly with the Forest Supervisor all matters relating to such use of National Forest land.
2. Agree to maintain improvements and premises to standards of repair, orderliness, neatness, sanitation and safety acceptable to the Forest
Supervisor and, in exercising the privilege authorized by this
Memorandum, comply with the regulations of the Department of
Agriculture and laws which are applicable to the area or operations covered by this Memorandum; and fully repair all damage, other than ordinary wear and tear, to National Forest roads and trails, resulting from the exercise of the privileges authorized by this Memorandum.
3. Agree to take all reasonable precautions to prevent and suppress forest fires. No material shall be disposed of by burning in open fires during the closed season established by law or regulations without the written consent of the Forest Supervisor.
4. Remove equipment from National Forest land within one year after termination of this agreement, or move equipment to new locations as needed or desired with concurrence of both parties, or as required by higher priority need as stated in Section A-4 above.
5. If any Weather Service installations or operations authorized under this
Memorandum cause interference to other Government communications systems, which are operating within IRAC tolerances, the Weather
Service will immediately verify and suspend operations until satisfactory corrective measures have been taken to restore Weather
Service communications equipment to IRAC and FCC tolerances. Costs for investigative and corrective measures to any or all Weather Service equipment will be assumed by the Weather Service. This encompasses radio communications, telemetry, radar, and radar adjuncts.

6. Agree that space for the installation and operation of radio-electronic type equipment is contingent upon the use of specific radio frequencies, types emission, band widths, RF power outputs, and under specific radio or electronic service classifications as authorized by IRAC for the specifically-named Federal Government deparment. The foregoing exact data will be shown on Form 2700-10 and approved by the Regional
Forester prior to installation of any such equipment. Any and all subsequent changes in, or additions to, the specified operation frequencies, types emission, band widths, RF power outputs, class of service, or the named fcc licensee, shall require advance notification of the Forest Supervisor.
7. Agree not to install or allow the installation of any foreign radioelectronic type equipment on or within the structure(s) or on the premises as may be authorized and covered by this Memorandum, without advance notification and joint-occupancy approval of the Forest
Supervisor; "foreign" radio-electronic type equipment in this instance meaning radio-electronic type equipment or installation which may be authorized by FCC license or IRAC agreement, but in a name other than that of the Weather Service or Forest Service authorized joint occupant.
8. Recognize that use of Wilderness Areas is restricted by the Wilderness
Act (Public Law 88-577); and that, while the Act recognizes valid uses of
Wilderness Areas, it generally precludes any structure or installation or the use of motorized equipment within such an area.
C. THE FOREST SERVICE AND THE NATIONAL WEATHER SERVICE
MUTUALLY AGREE:
1. That this Memorandum or Understanding may be terminated or amended at any time by mutual consent of the Forest Service and the
Weather Service. Following such termination, negotiations will be undertaken for a substitute agreement, if such is needed.
2. That upon final termination of this or any substitute Memorandum or
Understanding, the Weather Service will remove any improvements that have been erected, unless otherwise agreed upon in writing, and will leave the sites in a condition acceptable to the Forest Service. If determination is made to leave any said improvements in place, the
Weather Service, to the extent that it may lawfully do, will transfer said improvements to the Forest Service.

2. Responsibility. Director of Watershed Management, will represent the
Regional Forester as liaison with the Weather Service in matters relating to floods and flood forecasting.
The Director of Fire Management, will represent the Regional Forester as liaison in all other matters concerning cooperation between the Weather Service and the
Regional Forester.
3. Procedure. The foregoing Memorandum of Understanding will cover the construction, operation and maintenance of weather and streamflow data-gathering equipment not properly a part of current fire-weather forecasting arrangements.
The use of a specific site will be covered by a supplement to the Memorandum of
Understanding (Sample at Exhibit A). Forest Supervisors are authorized to approve and sign supplements for specific sites except as follows:
Regional Forester approval of sites within roadside zones, classified areas or proposed classified areas is required.
Regional Forester approval of electronic uses involving transmission and/or reception of telemetering, communication, radar and other electromagnetic radiation is required.
The Memorandum of Understanding will usually cover the use of a site, and there will be no need to add special conditions of use to a supplement. However, all possible situations could not be covered in the Memorandum of Understanding, and in some cases added conditions of use may be necessary to prevent conflicts with
National Forest management. The reverse side of a supplement provides space for the addition of any extra conditions which may be necessary.
Electronic equipment is an example of a use for which added conditions may be required. The Memorandum of Understanding covers the conditions necessary for the operation of minor electronic equipment such as radio telemetering. In some situations it may be appropriate to authorize, with a supplement, a major electronic installation such as radar or communications. The sample supplement used in these instructions is for a major electronic installation, and the added conditions shown are those required for such an installation.

The Weather Service will complete and sign the front side of a supplement to the
Memorandum of Understanding as an application for the use of a site. Upon receipt of such an application, the following steps should be taken by the Forest Supervisor to complete the supplement and approve use of the site:
Examine the site to assure that its use as applied for is compatible with
National Forest management. Reasonable permanency of an installation will generally be required, and this is assured by item A. 4. of the Memorandum of
Understanding. Therefore, an impact survey shall be made, and decisions reached shall be documented in the case file.
Complete the supplement by adding any additional conditions, if necessary, for use of the specific site.
Forward the supplement to the Regional Forester for approval when required.
Sign the supplement. Distribution of a signed supplement shall include one copy to Recreation under 2740 designation.
Current Weather Service special-use permits for weather and stream-flow datagathering equipment for other than fire weather forecasting purposes shall be converted to supplements to the Memorandum of Understanding.
