Historic Bridge Rehabilitation, Watertown, CTThe Skilton Road Bridge was orig-inally built in 1865 as a one lane, dry stone masonry arch bridge over the Skilton Gorge in Watertown. Rehabilitation in 1988 included strengthening of the stone mason-ry with reinforced concrete and adding concrete guide rails to the bridge. On December 10, 1991, the Skilton Road Bridge was added to the National List of Historic Places, and in 2013, the bridge was found to be structurally deficient.
Tata & Howard’s design for the re-habilitation and repair of the bridge required careful consideration of the historical nature of the struc-ture. The design was approved and construction took place in 2015. All structural deficiencies were ad-dressed and the project included the following:• Widened the bridge for two 9’ travel lanes
and a sidewalk;• Installed new aluminum bridge rails covered
with wood;• Repaired stone masonry on the west abutment wall;• Added new storm drainage.
Construction on the Skilton Road Bridge was completed in October of 2015, and a ribbon cutting ceremony was held on December 10, 2015. The bridge maintains its his-toric integrity.

T&H Consolidates Connecticut OfficesT&H consolidated its two Connecticut offices into one cen-trally-located branch in Waterbury, Connecticut. The consol-idation is largely a result of T&H’s acquisition of Waterbury engineering firm Roald Haestad, Inc. in August of 2014.
“After the acquisition of Roald Haestad, we knew we wanted to combine our two Connecticut offices into one cohesive team to better serve our clients,” said Steve Rupar, P.E., Vice President. “Because we also wanted to ensure the satisfaction of our em-
ployee-owners and to retain our incredible talent base, we decided to proceed gradually over the course of 2015. The move was finalized at the end of the year.”
Currently, the office is providing engineering services for numerous Connecticut clients including the South Central Connecticut Regional Water Authority (RWA), Aquarion Water Company, and the Cities of Dan-bury, Norwalk, New Britain, and Meriden.
“The consolidation makes financial sense and also enhances our teamwork – which is one of our corporate values, and what sets us apart from the competition,” added Sal Longo, P.E., Vice President. “The move was completed smoothly with no interruptions to our projects or inconvenience to our clients. We were fortunate to retain our valued team members, and we are all looking forward to a successful 2016.”

We are passionate about improving the environment in which we live through our work — and works. Both as a corporation and as individuals, we believe in giving back, and we encourage and support charitable works of all employee-owners.
Wastewater Engineering Services in Coolidge, Arizona
On February 8, the Coolidge, Arizona City Council approved an agreement with Tata & Howard for work on four wastewater proj-ects, as follows: • Prepare bid documents for the rehabilitation of up to 12 man-
holes that are experiencing signs of severe corrosion;• Conduct an evaluation of the hydrogen sulfide issues with-
in the City’s collection system that is causing corrosion, odor, and potential health and safety problems;
• Evaluate the replacement of the existing headworks auger based on existing operating conditions and recent bids re-ceived for a new auger, and provide an evaluation of addition-al long term concerns associated with the headworks of the wastewater treatment plant and possible reasons the lifespan of the headworks auger is being shortened; and
• Prepare bid documents for the replacement of the existing headworks auger suitable for solicitation of bids for the work.
Navajo Water Crisis Tata & Howard sponsored a water cistern through Navajo Water Project, a subsidiary of DIGDEEP that works to provide safe, accessible drinking water to Native Americans living in Navajo Nation. The 1,200-gallon cistern provides the necessary water storage for a full running water system in one Navajo American Home. The gift was purchased in honor of Tata & Howard’s clients in lieu of holiday cards.
Water For PeopleTata & Howard employee-owners, with a 100% match from the company, donated just shy of $10,000 to Water For People in 2015. Water For People is Tata & Howard’s charity of choice to which employee-own-ers donate through automatic payroll de-ductions.
Dare Family ServicesTata & Howard partnered with Dare Family Services this past holiday season to provide requested gifts to disadvantaged children in Massachusetts. Dare Family Services’ primary mission is to find, train, and sup-port loving homes that will help children become resilient and overcome the trauma of serious abuse and neglect.

In The NewsEPA Anticipates MS4 Permit to be Released Imminently
EPA and MassDEP held a briefing at the State House in December to update legislators on MS4 permits. EPA then stated the anticipated permit would be released as early as mid-January 2016. However, at the time this newsletter went to press, the permit is still pend-ing.
The draft permit received over 1,400 comments to which EPA is in the pro-cess of responding. The legislators in attendance expressed concern over the costs to communities to comply, partic-ularly since towns’ estimated costs for compliance were considerably higher than originally stated by EPA. EPA said that costs could potentially be adjust-ed once the permit was released, and also affirmed that costs to communities with TMDLs or impaired waters would be significantly higher in order to suf-ficiently address water quality issues. However, EPA also stressed that the im-pending permit is strictly for planning purposes and will not require construc-tion of Best Management Practices.
MassDEP is currently reviewing all changes that EPA proposes to make to the permit. MassDEP is particularly interested in seeing if comments that Commissioner Marty Suuberg had previously submitted on the draft have been incorporated into the final permit.

Class C Bronson E. Lockwood Dam, Bethlehem, CT
CT DEEP Issues New EAP Requirements for High Hazard and Significant Hazard Dams
The State of Connecticut Department of Energy and Environmental Protection (DEEP) recently adopted Regulation 22a-411a concerning the preparation and update of Emergency Action Plans (EAPs) for High Hazard (Class C) and Significant Hazard (Class B) dams. EAPs meeting the new requirements for Class C dams must be submitted to DEEP within 12 months of February 3, 2016, the effective date of the new regulation, and within 18 months for Class B dams. Dam owners will be required to submit an updated EAP every two years thereafter, or more frequently as necessary to reflect significant changes to the dam structure or downstream area.
An EAP is intended to be a pragmatic document that both identifies conditions that require a response and provides clear instructions in an emergency situation. “The new requirements for dam owners min-imize the potential for dam failures and increase public safety by di-recting owners to improve oversight and responsibility for their dams through the preparation of Emergency Action Plans (EAPs) and regu-lar inspections,” said DEEP Commissioner Robert Klee.
The new EAP regulations include criteria for inundation mapping, dam monitoring procedures, formal warning notification and commu-nication procedures, and EAP review and revisions. Copies of the EAP must be filed with the DEEP, the chief executive officer, and the emer-gency management officer of any municipality that would potentially be affected by an emergency involving the dam for which the EAP has been prepared.
For more information, or for assistance meeting the new requirements for Dam EAPs, please contact us at [email protected].

Century-Old Dam Rehabilitation, Shelton, CTThe Means Brook Reservoir Dam, a concrete gravity dam constructed on rock in 1916, required repairs in order to improve the safety and reliability of the structure, replacement of the deteriorated upstream and downstream faces of the dam and the crest, and rehabilitation and modernization of the gate chambers. Hydraulic, hydrologic, and structural studies over the last several years have shown that the dam would be overtopped by about 3.9 feet by the Probable Maximum Flood (PMF), and that the dam does not have adequate stability factors of safety for this extreme loading condition. The upstream and downstream faces and the crest of the dam were severely spalled and delaminated, and the dam reportedly overtopped by about four inches during the 1955 flood. In 1977, the spillway was extended to its current length of 100 feet and a 2.1-foot high concrete parapet wall was constructed along the upstream crest of the dam.
Concrete repairs were made to the crest and both faces of the dam. Rock anchors were installed and post-tensioned in holes drilled through the dam into the rock foun-dation. One section of the spillway training wall was removed and replaced. The deteriorated concrete on the remaining sections was re-
moved and the wall resurfaced. The repairs and improvements undertaken to the gatehouse and chambers included reshingling the gatehouse roof, providing a new steel plate exterior door for additional security, and blocking up the existing windows. In addition, the electrical system, ladders, stairs, sluice gates and their appurtenance, a butterfly valve, and hatches were all replaced.
Chain link fence was installed along portions of the spillway training wall for safety, and chain link fence and gates were installed at both ends of the dam for security. In addition, galvanized steel pipe railings were installed along the upstream and downstream crest of the dam for safety. Steel pipe rails were chosen for the dam crest instead of chain link fence because the dam crest is subject to overtopping.
Wastewater Treatment Facility Upgrades in Saxtons River, VT
Tata & Howard is currently providing engineering services for upgrades to the Saxtons River Wastewater Treatment Facility in Saxtons, Vermont. Services include the design of a new two tank Sequencing Batch Reactor (SBR), a new headworks with a fine screen and an aerated grit chamber, intermediate pump station, medium pressure UV disinfection, conversion of the existing clarifier to an equalization basin with a pump station, design of a new two compartment aerated sludge holding tank, and miscellaneous improvements to the existing control building, including a pellet boiler for the plant heating system.
The SBR process was originally recommended by T&H to Saxtons River Trustees at a meeting, and was chosen as the best alternative over three other plans presented by another engineering firm. SBR uses ultraviolet (UV) light instead of chlorine to treat wastewater. Not only is the SBR option the most economical, but it is also a green initiative. UV utilizes only light, and therefore eliminates all processes associated with the handling and transport of chemicals, making it safer for operators and aquatic life.
Construction is anticipated to be completed by the end of 2017. T&H is providing construction administration and resident observation services.

Environmental Services in MAT&H provided peer review on work that had been completed at a former lumber mill, and all documentation that had been prepared to date was reviewed. The primary concern was an area where pressure treated lum-ber had been stored, as the lumber was treated with chromated copper
arsenate and the residual arsenic concentrations in soil were very high. The previous recommendation was to put a deed restriction (specifi-cally, an Activity and Use Limitation or AUL) on the area to limit the exposure. Because the planned future use for the property is to con-vert the existing mill building into residential condominiums, this ap-proach was inadequate. In an effort to find a more suitable solution, T&H obtained and analyzed additional soil samples from this area and found that less than 200 cubic yards had been affected. The contam-inated soil can be removed for under $30,000 and will bring residual concentrations below that allowed for residential use.
Because the mill is located on a brook, a filing with the local Conserva-tion Commission was required. T&H suggested that, due to the limit-ed work being done and the fact that the affected area is separated from the brook by a retaining wall, an Abbreviated Notice of Intent (ANOI) would be sufficient. The Conservation Commission agreed, and the ANOI was approved at a Public Hearing. T&H is currently in the pro-cess of preparing a Release Abatement Measure (RAM) Plan, which must be submitted to the MassDEP prior to excavation.
