These costs include labor, outside contractor costs, fuel, generator rental and other directly related expenses resulting from storm damage mitigation, repair, clean-up and restoration activities. Middlesex has submitted claims for these costs through its insurance carrier and has received an initial payment of $0.2 million. Middlesex will seek recovery of any Superstorm Sandy related costs not recovered through insurance in its next base rate proceeding. Middlesex cannot predict whether there will be any remaining costs after the insurance claim is closed or, if there are any remaining costs, whether they will be recovered in its next base rate proceeding. In April 2013, the NJBPU approved a Middlesex Petition to establish a Purchased Water Adjustment Clause and implement a tariff rate sufficient to recover increased costs of $0.1 million to purchase untreated water from the New Jersey Water Supply Authority (NJWSA) and treated water from a non-affiliated regulated water utility. In November 2012, Middlesex filed a Petition with the NJBPU seeking approval of foundational information (Foundational Filing) that would allow for the implementation of a Distribution System Improvement Charge (DSIC). A DSIC is a rate-mechanism that allows water utilities to recover investment in capital improvements to their water distribution system made between base rate proceedings. In February 2013, the Foundational Filing was approved by the NJBPU, which allows Middlesex to implement a DSIC rate to recover costs for qualifying projects that are placed in service in the six-month post-approval period. The DSIC rate is allowed to increase in three subsequent six month periods for any additional qualifying projects placed in service during those time periods. The maximum annual revenue allowed to be recovered under the approved Foundational Filing is $1.4 million. Middlesex expects to receive approval to implement a DSIC rate in the fourth quarter of 2013 designed to generate annual revenues of $0.3 million. Pinelands - In March 2013, the NJBPU approved a combined $0.2 million increase in Pinelands Water and Pinelands Wastewater’s annual base revenues. In its initial request, filed in August 2012, Pinelands had sought an increase of $0.3 million on a combined basis. The rate increase for the water service, which is approximately 50% of the approved increase, will be phased-in over one year. TESI - On October 1, 2013, TESI closed on its DEPSC-approved purchase of the wastewater utility assets of the Plantations development (the Plantations) for $0.4 million and began providing wastewater services to the 600 residential customers in the Plantations in Delaware. Annual revenues for serving the Plantations are expected to be approximately $0.2 million. Effective one year after acquisition, subject to completion of agreed-upon capital improvements to the Plantations wastewater system, TESI will be allowed to implement a 33.5% base wastewater rate increase.
