(c) Assignments proposed in accordance with the railroad industry radio frequency allotment plan along the United States-Canada borders utilized by the Federal Communications Commission and the Department of Transport, respectively, may be excepted from this arrangement at the discretion of the referring Agency.

(d) Assignments proposed in any radio service in frequency bands below 470 Mc/s appropriate to this arrangement, other than those for stations in the Domestic Public (land mobile or fixed) category, may be excepted from this arrangement at the discretion of the referring Agency if a base station assignment has been made previously under the terms of this arrangement or prior to its adoption in the same radio service and on the same frequency and in the local area, and provided the basic characteristics of the additional station are sufficiently similar technically to the original assignment to preclude harmful interference to existing stations across the border.

2. (a) For Bands below 470 Mc/s, the areas which are involved lie between Lines A and B and between Lines C and D, as follows:

Line A — Begins at Aberdeen, Wash. running by great circle arc to the intersection of 48° N., 120° W.,thence along parallel 48° N., to the intersection of 95° W., thence by great circle arc through the southernmost point of Duluth, Minn., thence by great circle arc to 45° N., 85° W., thence southward along meridian 85° W., to its intersection with parallel 41° N., thence along parallel 41° N., to its intersection with meridian 82° W., thence by great circle arc through the southernmost point of Bangor,Me., thence by great circle arc through the southernmost point of Searsport, Me., at which point it terminates; and

Line B — Begins at Tofino, B.C., running by great circle arc to the intersection of 50° N., 125° W., thencealong parallel 50° N., to the intersection of 90° W., thence by great circle arc to the intersection of 45° N., 79° 30' W., thence by great circle arc though the northernmost point of Drummondville, Quebec (Lat: 45° 52' N.,Long: 72° 30' W.), thence by great circle arc to 48° 30' N., 70° W., thence by great circle arc through the northernmost point of Campbellton, N.B., thence by great circle arc through the northernmost point ofLiverpool, N.S., at which point it terminates.

Line C — Begins at the intersection of 70° N., 144° W., thence by great circle arc to the intersection of 60°N., 143° W., thence by great circle arc so as to include all of the Alaskan Panhandle; and

Line D — Begins at the intersection of 70° N., 138° W., thence by great circle arc to the intersection of 61° 20' N., 139° W. (Burwash Landing), thence by great circle arc to the intersection of 60° 45' N., 135° W.,thence by great circle arc to the intersection of 56° N., 128° W., thence south along 128° meridian to Lat. 55°N., thence by great circle arc to the intersection of 54° N.,130° W., thence by great circle arc toPort Clements, thence to the Pacific Ocean where it ends.

(b) For all stations using bands between 470 Mc/s and 1000 Mc/s; and for any station of a terrestrial service using a band above 1000 Mc/s, the areas which are involved are as follows:

  1. For a station the antenna of which looks within the 200E sector toward the Canada-United States borders, that area in each country within 35 miles of the borders; and
  2. For a station the antenna of which looks within the 160E sector away from the Canada-United States borders, that area in each country within 5 miles of the borders;
  3. The area in either country within coordination distance (paragraph 7) of a receiving earth station in the other country which uses the same band.

(c) For bands above 1000 Mc/s, coordination of an earth station is required if any portion of the Canada-United States borders lies within the coordination distance (paragraph 7) of the earth station.

3. (a) Each Agency shall furnish the other with a complete frequency assignment record, including, among the basic characteristics reported, the date of first usage of each frequency by each of the stationsshown regardless of the class of service, which were in actual operation on October 1, 1960, and located in the areas indicated in 2(a) above for the frequency bands below 470 Mc/s, and located in the areas indicated in 2(b) above for the frequency bands above 470 Mc/s. For the purpose of the revised arrangement, such record shall constitute, together with the 6th Edition of the Radio Frequency Record (Volume III), the master frequency assignment records for the two Agencies upon acceptance by the other agency. Accordingly, in implementing the Geneva (1959) Radio Regulations, as amended by the EARC, Geneva 1963, each Agency shall use these frequency records, in lieu of subsequent I.T.U. records, in matters leading to the resolution of pertinent cases of harmful interference involvingstations authorized by the two Agencies.

(b) Each Agency shall keep its frequency assignment data in the aforementioned records current through the submission to the other Agency of its recapitulative master frequency assignment records at intervals of three months.

4. (a) Before the Federal Communications Commission takes final action on any application for the use of any frequency in the bands herein, in the areas stipulated in paragraphs 2(a), 2(b)(1) and 2(b)(2) above involving an effective radiated power in excess of five watts, or if protection is desired for an operation involving a power of five watts, or less, it will refer the pertinent particulars of the proposed assignment (see Appendix 3, 4 or 5 as appropriate), in the form shown in Appendix 1 hereof, to the Department of Transport for comment as to whether the granting of an authorization will be likely to result in the causing of harmful interference to any existing Canadian assignments authorized by the Department.

(b) Before the Department of Transport takes final action on any application for the use of any frequency in the bands herein, in the areas stipulated in paragraphs 2(a), 2(b)(1) and 2(b)(2) above involving an effective radiated power in excess of five watts, or if protection is desired for an operation involving power of five watts, or less, it will refer the pertinent particulars of the proposed assignment (see Appendix 3, 4 or 5 as appropriate), in the form shown in Appendix 2 hereof, to the Federal Communications Commission for comment as to whether the granting of an authorization will be likely to result in the causing of harmful interference to any existing United States assignments authorized by the Commission.

(c) Before either Agency takes final action on any application for use of any frequency in the bands herein which are allocated to a space service, in the area stipulated in paragraph 2(b)(3) above, regardless of the power involved, it will refer the pertinent particulars of the proposed assignment (see Appendix 3, 4 or 5 as appropriate), in the applicable form shown in Appendix 1 or 2 hereof, to the other Agency for comment as to whether the granting of an authorization will be likely to result in the degrading of the previously agreed protection to a receiving earth station.

(d) Neither the Federal Communications Commission nor the Department of Transport shall be bound to act in accordance with the views of the other. However, to keep such instances to a minimum, each Agency should cooperate to the fullest extent practicable with the other by furnishing such additional data as may be required.

5. Whenever differences of opinion concerning the probability of harmful interference exist, which cannot be resolved otherwise, or in cases where the information available makes it difficult to determine whether harmful interference would be created by the granting of a particular authorization, arrangement should be made for actual on-the-air tests to be observed by representatives of both the Federal Communications Commission and the Department of Transport. Should harmful interference be caused to the existing station, the Agency having jurisdiction over the proposed station should be notified promptly so that the transmission of the interfering station may be halted. In the absence of a complaint of harmful interference, the authorization may not be granted until a lapse of 30 calendar days following the test period to allow sufficient time for the exchange, if desired, of engineering or other comments indicating an objection to the assignment.

6. In the interest of planned use of the spectrum, information concerning future expansions and adjustments of the several services allocated to use the above bands, in the areas stipulated above, shall be exchanged to the maximum extent practicable.

7. Coordination distance shall be the distance, calculated for any station, according to Recommendation 1A of the Final Acts of the EARC, Geneva, 1963.
