¶ 1. April 2, 2007. Several neighbors of St. Mary's Star of the Sea Church in Newport, Vermont (collectively, "neighbors") appeal an Environmental Board order finding that Verizon Wireless's proposed construction on the land and in the towers of the Church is exempt from Act 250 jurisdiction. Neighbors also appeal the Board's preliminary decision to deny them party status under certain Act 250 criteria. We affirm.
¶ 2. In November 2002, Verizon Wireless requested a jurisdictional opinion from the District 7 Environmental Commission to determine whether it required an Act 250 land-use permit to proceed with its proposed project — installing three cellular-panel antennas and three personal-communication-services antennas within the Church's existing bell towers and constructing an equipment shelter in the parking lot adjacent to the Church. The Assistant Coordinator issued an opinion, finding that the project was exempt from Act 250 jurisdiction under
¶ 3. In November 2004, Verizon Wireless filed a petition for declaratory ruling with the Board regarding the Act 250 jurisdictional issue. Neighbors requested party status under Act 250 criteria 1 (noise), 5 (traffic safety and congestion), 8 (aesthetics and historic impacts), 9(K) (public investments), and 10 (local and regional planning). See
¶ 4. Neighbors now challenge the Board's denial of party status under *590 criteria 5 and 9(K),* and its ultimate decision that Verizon Wireless's proposed project does not amount to a substantial change to the Church, the preexisting development, and that Act 250 jurisdiction is therefore inappropriate.
¶ 5. First, we consider neighbors' contention that the Board erred in denying them party status under Act 250 criteria 5 and 9(K). Under Environmental Board Rule (EBR) 14(A)(5) and (6), the Board may grant party status to persons "who demonstrate[] an interest under any of the criteria listed at
¶ 6. We review the Board's decision to deny party status to neighbors under Act 250 criteria 5 and 9(K) for abuse of discretion, and will reverse only upon finding that the Board `"withheld its discretion entirely or . . . exercised [discretion] for clearly untenable reasons or to a clearly untenable extent.'" In re Putney Paper Co.,
¶ 7. Next, we evaluate neighbors' challenge to the Board's final ruling regarding Act 250 jurisdiction over Verizon Wireless's proposed project. In considering neighbors' arguments, "we apply a deferential standard of review." In re EHV-Weidmann Indus., Inc.,
¶ 8. It is undisputed by the parties that because the Church was built before 1970 it is a "preexisting development" and is thereby exempt from Act 250 jurisdiction. See
¶ 9. We cannot agree with neighbors that the Board erred when it analyzed Verizon Wireless's project under § 6081(b), rather than as a new development. The Board rejected neighbors' contention that the project should not be grandfathered under § 6081(b) because it is a "new and separate commercial interest that is unaffiliated with the Church," finding that drawing such distinctions in purpose would "cause identical construction to be treated differently." More specifically, it would result in the project "be[ing] subject to jurisdiction but identical towers installed by the Church to broadcast religious messages" remaining outside of Act 250 jurisdiction. Such an interpretation of the exemption would lead to an irrational consequence, and the Board was justified in rejecting it. Brawn v. Bd. of Dental Exam'rs,
¶ 10. Finally, we uphold the Board's decision that Verizon Wireless's proposed project does not amount to a substantial change to the Church and is therefore exempt from Act 250 jurisdiction. Once a project is determined to fall within § 6081(b), the burden shifts to the proponents of jurisdiction to demonstrate that the project represents a substantial change to the preexisting development. In re Hale Mountain Fish GameClub, Declaratory Ruling # 435, memorandum of decision, at 2-4 (Sept. 24, 2004). A "substantial change" is defined as "any change in a development . . . which may result in significant impact with respect to any of the [Act 250] criteria." EBR 2(G). We have repeatedly upheld the Board's two-pronged substantial-change test. Under the test, the Board first determines whether a cognizable change to the preexisting development will result from the project, and, if so, whether it has the potential for significant impact under one or more of the Act 250 criteria enumerated in
¶ 11. Under prong one of the test, the Board found that "both the installation of the antennas in the bell towers and the construction of the equipment building" were cognizable changes to the Church; the Board then went on to analyze the potential for significant impacts on aesthetics and historic value of the site (criterion 8), and conformance with the city plan (criterion 10) under the second prong of the test. At a site visit conducted in June 2005, the Board viewed the Church property, including nonfunctioning antennas in the west tower installed by Verizon Wireless at the request of the District Commission, and *592
noted the "moderate" ambient noise level at the location of the proposed equipment shelter. Based partly on its site visit, the Board found that the "present mesh screening prevents clear views through the bell towers," and that the proposed screens would improve views through the towers. Furthermore, the Board observed that while the antennas were visible through the openings in the bell towers, they did not "significantly detract from the Church's overall visual aesthetic quality." Taking into consideration the evidence presented by neighbors and the observations made on the site visit, the Board concluded that neither the proposed cell towers nor the equipment shelter would have "significant visual impacts on the aesthetics of the area" or "any impacts on the ambient noise levels in the area." See In re Quechee LakesCorp.,
¶ 12. Concerning any impacts on the historic value of the Church, the Board noted in its analysis that the only documentary evidence presented on the issue was a letter from the Vermont Division for Historic Preservation opining that the project "will have no adverse effect to this historic resource." Thus, the Board concluded that neighbors had failed to meet their burden of proof as to that criterion.
¶ 13. Lastly, as to criterion 10, the Board found that neither party indicated any particular section of the Newport City Plan that would be applicable to the proposed project, but rather focused on sections of the city's zoning bylaws. The Board thus cited to the Environmental Court's ruling in a related case on the issue of the project's compliance with the local zoning bylaws, which indicated that any claims neighbors might raise as to the city plan relevant to criterion 10 were not likely to rise to the level necessary to find jurisdiction under the Board's substantial-change test. In re Curtis, Docket No. 231-12-03 Vtec (Jan. 24, 2005). While the Environmental Court's ruling was, at the time, being appealed to this Court, we have since upheld that decision in In reCurtis,
¶ 14. We fail to find error with the Board's substantial-change analysis under criteria 8 and 10 of Act 250. The Board's conclusions were based on the evidence presented by the parties and the Board's own site visit to the Church. Neighbors had the burden of proving that Verizon Wireless's project would create a substantial change to the Church with regard to its aesthetics and historic value, or compliance with the city plan, and they did not meet that burden. On appeal, neighbors have not presented sufficient evidence of error to override our deference to the Board's Act 250 *593 jurisdictional determinations, and we therefore affirm.
Affirmed.
