Thomas Chief, Office of Engineering and Technology Federal Communications Commission 445 12th Street, S.W. Washington, D.C. 20554 Re:Geophysical Survey Systems, Inc. Request for Waiver of Section 15.509(d) FCC ID QF7TERRAVISION, EA637896 (GPR Device) Dear Ed: Pursuant to Section 1.3 of the Commission's Rules, Geophysical Survey Systems, Inc. (GSSI) requests a waiver of Section 15.509(d) to permit the certification of a GPR device ("Device") whose emissions are slightly above the prescribed limits at isolated frequencies. GSSI filed a certification application for the Device on May 14, 2003, under FCC ID QF7TERRAVISION, EA637896. IMPORTANT: Following an exchange with Commission laboratory staff, GSSI submits this request to replace one filed on May 23, 2003 (which in turn replaced one filed on May 14, 2003). Please set aside both previous versions and consider this one. TECHNICAL CONSIDERATIONS The measured emissions data for the Device are attached. It shows the emissions are slightly over-limit at the following frequencies: Edmond J. Thomas June 12, 2003 Page 2 Freq. (MHz) Over Limit (dB) Allocation 34.141.3Fed. Gov. Fixed & Mobile 35.581.0Public Mobile; Private land Mobile 46.183.6Private Land Mobile 213.900.3TV channel 13 291.901.5Fed. Gov. Fixed & Mobile The slight power increase requested by GSSI cannot realistically have any adverse effect in any of these bands. GSSI has carefully shielded the Device. The transmitter consist of two arrays of seven antennas each, as shown in the attached photograph. Each of the seven antennas is separately enclosed in an aluminum box on all four sides and the top. Then the assembled array is enclosed in yet another aluminum box, also closed on all four sides and the top. Most of the measured emissions result from unavoidable leakage between the lower edge of the shielding and the ground surface. For that reason, further efforts at shielding are unlikely to significantly reduce emissions, and in any event would make the Device too unwieldy for use in the field. Even by GPR standards, the Device will be manufactured and used in very small numbers. The Device is 6 feet wide, weighs 500 pounds, and will cost the end user approximately $100,000. GSSI projects a total U.S. market for the Device of six or fewer units per year. This handful of units will be used at widely separated locations and operated over short duty cycles. For these reasons as well, there is no significant possibility of interference. PUBLIC INTEREST CONSIDERATIONS The Device is designed specifically to survey very long pipeline installation sites. Its purpose is to detect and locate obstacles and buried infrastructure prior to excavation for the pipeline, in order to avoid interruption to buried utilities and forestall public safety hazards (as from cutting though gas lines). When surveying a proposed pipeline route, the Device collects a 3D image that is typically 6 feet wide, 12 feet deep, and as long as necessary -- in a single pass at 5 mph. (Achievable depth varies with the type of soil.) The image obtained shows all previously installed pipes and telecommunications lines, so that installation of the new pipe can be Edmond J. Thomas June 12, 2003 Page 3 1 WAIT Radio v. FCC, 418 F.2d 1153, 1157 (D.C. Cir. 1969). accomplished without damage to existing infrastructure. This image is invaluable from the standpoints of both public safety and communications reliability. The Device requires the waiver to deliver its full benefits. Without the waiver, GSSI must cut back either the pulse repetition frequency (PRF) or the output power. Either step would seriously impair performance. At a PRF low enough to achieve compliance, the Device must be moved across the ground at impractically slow speeds. And cutting back output power reduces the imaging depth, with a consequent risk of missing underground installations. Specifically, reducing the power to achieve compliance would reduce the useful scan depth by about 20 percent. This may not seem like a large value, but that 20 percent is important to safe excavation. In the example above, the visible depth would deteriorate from 12 feet to about 9.5 feet -- and would completely miss underground installations in the 9.5-12 foot range. The Device, with its fourteen antennas, executes fourteen parallel scans in one pass. The alternative requires marking off the area to be investigated and moving a single antenna over the same course fourteen times. That is a slow and expensive process. When the area to be investigated involves a street or highway, it must be closed for the duration of the measurements, adding cost, inconvenience, and unnecessary risk for both the operator and the public. LEGAL CONSIDERATIONS This request complies with the waiver standards set out by the U.S. Court of Appeals for the D.C. Circuit. That court held: [A] general rule, deemed valid because its overall objectives are in the public interest, may not be in the "public interest" if extended to an applicant who proposes a new service that will not undermine the policy, served by the rule, that has been adjudged in the public interest. 1 The conditions set out by the court as mandating consideration of a waiver are thoroughly met here. Grant of the requested waiver will increase the availability of devices that provide safety-of-life applications and other important benefits that are plainly in the public interest, without any negative consequences. Edmond J. Thomas June 12, 2003 Page 4 2 Id., 418 F.2d at 1157 ("[A]llegations such as those made by petitioners, stated with clarity and accompanied by supporting data, are not subject to perfunctory treatment, but must be given a 'hard look.'") Accordingly, a waiver is in the public interest, and is amply entitled to the "hard look…
