Findings: · Trees have great value, both aesthetic and economic, and Connecticut residentsnot only take great pride in their beauty, but benefit significantly from them. Testimony presented by the Urban Forestry unit of DEEP showed the heating and cooling costs of a home were lowered with the presence of appropriate trees. · Trees knocked down 90% of the utility wires that fell in Tropical Storm Irene.· Data presented to the Two Storm Panel indicated that Connecticut has one of themost dense tree canopies in the United States (# 1 in the U.S. for our Wildland/Urban Interface tree density). Connecticut’s tree profile, also, revealed trees with larger circumferences than average. UIL Holdings estimated that over 300,000 trees are planted in the utility pole rights of way (ROW) in its 17 town territory. · Tree trimming and removal budgets consist of four sources:Source of Tree Trimming Budget Amount of Budget Municipal (Used primarily for maintaining health of town trees, not for utility rights-of-way) Approximately $10 million a year Connecticut Dept. of Transportation (Used primarily for roadway clearance and safety) $550,000 per year Telecommunications companies Failed to provide a tree trimming budget to Two Storm Panel CL&P (For 143 towns) $24,625,000 UI (For 17 towns) $3,418,883 · In its proposal to harden or strengthen its pole and wire infrastructure that CL&Psubmitted to the Two Storm Panel, the company recommended that they be approved to spend $366 million over the next ten years, essentially a 50% increase over what CL&P spent in the previous ten years, on tree trimming and vegetation management. · There does not exist in Connecticut specific industry standards for tree trimmingaside from the safety standards in ANSI Z 133.1 and OSHA 1910.269 and the operation standards in the ANSI A 300 series to direct the actions of tree wardens or of those performing utility pruning. · There are also no criteria by which a person may be appointed a tree warden.Recommendations: 20) Conduct a state -wide tree risk assessment and prioritization scheduleparticularly targeting hazardous trees. 21) Establish a state-wide Hazardous Tree Removal Fund that will providematching grants to homeowners for the removal of trees on private property that endanger utility wires. 22) 1.5 % of all funds approved for utility vegetation management by PURAshould be used to fund the private property Hazardous Tree program for 5 years. 23) Establish a State Vegetation Management Task Force (SVMTF) that willdevelop standards for road side tree care in Connecticut, vegetation management practices and schedules for utility rights of way, right tree/right place standards, licensing standards for tree wardens, municipal tree inventories and pruning schedules. This Task Force should consist of State, municipal, utility and nonprofit environmental organizations. The Commissioner of the DEEP or his/her designee should be its Chairperson. 24) DEEP should convene appropriate State agencies, municipalities and utilitiesfor the purpose of creating a 5 year collaborative effort for an enhanced tree maintenance program and the development of an educational effort regarding the use of appropriate and diverse tree species in both public and private spaces. 25) At least four entities—electric utilities, municipalities, telecom utilities, and theState of Connecticut—engage in tree trimming/removal activities that may protect the necessary infrastructure. On a semiannual basis, these activities should be coordinated amongst them to maximize the effectiveness of each entity and goals/targets should be established. This activity would be monitored through the SVMTF. 26) Increase DOT Tree Maintenance budget by $1 million a year for three yearsfor road/ tree safety program. 27) Legislation should be adopted providing for the removal of “hazard trees” fromprivate property by utilities or municipalities, which should include reasonable protections for property owners. INFRASTRUCTURE HARDENING Findings: · Electric and telecom utility general maintenance was insufficient to effectivelyprotect the existing “pole and wire” infrastructure from natural disaster, specifically the impact of falling trees/limbs on this infrastructure. · The panel reviewed several analyses of underground cable costs and feasibilityin Connecticut, using data from other states to make estimates on cost and feasibility/effectiveness. · The utilities have maintained that undergrounding is not feasible in many areasdue to cost factors and damage caused by traffic, weather, and condensation. The majority of studies that were reviewed, however, indicated that the appropriate installation of underground cables protected the cables from traffic and frost, and a common system of condensation elimination, used in many states in extensive underground systems, prevented damage caused in this way. · In addition, the cost of underground cables in many areas, especially city andtown centers, is not drastically different from that of above-ground utilities, due to the absence of impediments below the surface (i.e, ledge). Recommendations: 28) The Panel recommends that undergrounding be immediately studied byDEEP in the areas discussed by the Panel and the utilities. Such study should encompass feasibility of such undergrounding, the costs associated with the undergrounding, as well as potential reliability issues associated with undergrounded assets. 29) Selective undergrounding of utilities and strengthening assets beyond therequirements of the National Electric Safety Code (e.g., use of composite poles and spacer cable) should be recommended to PURA, with the cost shared between ratepayers and shareholders. All work should be permitted by municipalities, and the utilities should be required to pre-plan with other utilities with above-ground or below ground assets to reduce all costs for upgrades, bringing evidence of such cooperation as a requirement for local permitting. 30) Pole custodians should develop an audited list of assets, including age ofassets and wind load, to better assist in managing a work plan for asset strengthening. This list should be provided to the newly-created pole administrator position (discussed in Chapter 8, Recommendation 74 of this document) on an annual basis. 31) As one utility needs to expand or build new infrastructure, it should consultwith other utilities, and where possible, co-locate such expansion with other utilities to minimize the cost of burying them underground. Such an effort would need to be coordinated through a combination of PURA and the Siting Council so that utilities could be co-located. |
