Hedged transactions accounted for 51,360 MWhs or 83% of this volume (87% of forecasted load) at a cost of $3.56 million. Spot Market purchases resulted in a PJM charge of $639 thousand (a $662 thousand charge in the Day Ahead market and a $23 thousand credit in the Real Time market). Other PJM related charges accounted for an additional cost of $1.53 million, inclusive of all load related fees. The May Energy Only Unit Cost, excluding capacity obligations and credits, was $2.16/MWh favorable compared to the budgeted value of $80.01/MWh. On January 24, 2011, the City of Dover reviewed and approved Pace’s and NAES’ submittal of a revised budget for Dover’s FY2010-11 (the “Reset Budget”). The purpose of this Reset Budget was to provide a mid-year update as to the anticipated cost-of-service for FY2010-11. Dover’s projected all in Cost of Service for FY2010-11 is $89.87/MWh, or $0.58/MWh favorable as compared to the Reset Budget1. Generation and Asset Management Net generation for the month of May credited by PJM was 1,218 MWhs and the budget did not expect any generation. On May 31 both McKee Unit 3 and Van Sant Unit 11 were dispatched by PJM. In aggregate, Dover’s units were dispatched for 22 hours during the month, creating a generation production margin of $71 thousand (after fuel costs). The McKee units completed its spring outage on May 23 which started on March 28. On May 16, McKee units performed operational testing under natural gas and fuel oil to verify working status of controls modification made to the burner management system. 1 The projected all in Cost of Service is based on YTD actual results for 11 months and 1 month of projected costs. The Reset Budget was reviewed and approved by City of Dover. 2

Emissions Allowance Management Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet their 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover their 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Dover has the appropriate number of allowances were set aside for retirement (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NO x seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. 3

(3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $36,848.75 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $3.75/ton, 3976 post-CAIR SO2 allowances trading at $2.50/ton, 72 NOx annual allowances trading at $195/ton, and 52 NOx seasonal allowances trading at $17.50/ton.

The facility has now gone 229 days without an OSHA recordable accident and 229 consecutive days without a lost time reportable accident. There were zero Environmental Notices of Violations issued. There were three near miss events and three environmental deviations. Unit 3 was dispatched once and Unit 11 was dispatched twice with one of these dispatches later canceled. Monthly Budget Variance - The actual expenses attributable to O&M of the two sites for the month of May were $445,311. The expenses were $17,203 or 4.02% over the approved budget of $428,108. The principal reason for the negative variance is due to higher than budgeted expenses in electric and combustion turbine maintenance which were partially offset by lower costs in personnel expenses and materials. 2 Approximately 10 tons of NOx emissions resulted from the February 2010 McKee Run testing associated with the Pollution Remediation project and the June 2010 emission testing project. 3 The EPA reallocated 2 additional seasonal NOx allowances into the McKee Run 2011 account. 4

Risk Management Summary Forward PJM power prices were mixed since the last reporting period. Prices increased as above average temperatures were seen across much of the country, pushing the nearer term of the forward curve higher while the further out portion fell slightly. Forward Dover Zone power prices for FY 2011-2012, FY 2012-2013, FY 2013-2014, and FY 2014-2015 all changed by approximately -$0.91/MWh to $0.90/MWh (representing a range of a -1.50% decrease and a 1.71% increase, respectively) compared with the last reporting period.

2.2 – VARIANCE ANALYSIS Power Supply  Power Supply realized a favorable $48 thousand variance compared to the budget. This favorable variance was primarily due to the timing of Dover’s options purchase and payment of the associated premium. During FY2009-10 the City of Dover purchased Options as insurance to protect Dover from incremental energy cost exposure. The current City of Dover power supply and generation budget indicates that 100% of this purchase was expensed as a Power Supply Cost in the FY2009-10 period; however the FY2010-11 budget accrues this expense monthly.  PJM Charges for Load experienced a negative $186 thousand variance relative to the monthly budget. This variance was driven by Dover’s open position, which was 46% higher than budget. A larger volume of open positions, coupled with higher than projected PJM energy open prices, resulted in a total Open Position cost that was $307 thousand greater than budget. Additional factors contributing to the unfavorable variance included i) a $112 thousand unfavorable variance in PJM Ancillary charges and ii) a $27 thousand unfavorable variance in Transmission Loss Refunds. Offsetting these unfavorable variances were a $170 thousand favorable variances in Load Following and a $97 thousand favorable variance in Basis costs.  For the month the City realized a $138 thousand unfavorable net variance between Power Supply (fixed positions) and PJM Charges for Load (open positions, transmission, etc.). The change in volume resulted in an unfavorable $252 thousand variance, and the change in price resulted in a favorable $114 thousand variance. Hence, all of the unfavorable variance can be attributed to volume changes.  The Power Supply Management variance is merely an estimate at this point. Generation  Plant O&M reported an unfavorable variance of $17 thousand compared to the revised monthly O&M reset Budget of $428 thousand (the overall reset plant budget for FY 2010-11 was approved by the City Council on March, 2011). The timing of electric invoice and higher than expected combustion turbine maintenance resulted in unfavorable variance. 8

3.0 – ENERGY MANAGEMENT 3.1 – PURCHASED POWER Management Highlights  Dover’s May load was 62,114 MWh, which was 5.7% above the weather normalized load of 58,744 MWh. Hedge volumes accounted for 83% of actual load for the month.  The May All In Unit Energy cost (excluding capacity) of $77.85 per MWh is $2.16 per MWh lower than the monthly budget.

3.2 – GENERATION MANAGEMENT  PJM dispatched McKee Run Unit 3 and Van Sant Unit 11 on May 31st for 22 hours. Dover’s units generated 1,218 MWhs in aggregate for the PJM market and the budget did not expect any generation for the month.  The McKee units started a planned outage on March 28 that ended on May 23. On May 16, these units performed operational tests consuming 355 dth of natural gas and 754 gallons of fuel oil no.2. The testing fuel costs are expected under EG1112 and EG1113 projects.

Due to the conversion from #6 residual oil to low sulfur #2 oil, the need for a constant supply of natural gas to heat the #6 oil is no longer required. Some gas will still be required for winter space heating of the building(s). Pace will coordinate with NAES on the procurement of such supply. This expense will now fall under the plant’s utility costs and be paid and budgeted for by the station. Gas Transportation Purchased City of Dover decided not to renew agreements with the Eastern Shore Natural Gas Pipeline (“ESNG”) and TransCo to provide firm natural gas deliveries to the McKee Run and Van Sant stations. The City of Dover previously notified ESNG and TransCo of its intent to terminate these existing firm capacity agreements and, as a result, the City no longer pays firm demand charges or adjustments. ESNG FT Demand Charge $ 0 TransCo FT Demand Charge $ 0 Total Purchases $ 0 Other Gas Purchases Commodity and transportation imbalances on Eastern Shore Pipeline for the month resulted in no charge.

3.3 – EMISSIONS AND ALLOWANCE MANAGEMENT Given the regulatory uncertainty surrounding the allowance markets, Dover has elected not to include revenues from emission allowance sales in its 2010-2011 fiscal year budget. Dover purchased and retired 53 NOX seasonal allowances on November 23rd 2010, in order to meet their 2010 NOX seasonal compliance position. Additionally, Dover purchased 22 NOX annual allowances on February 11, 2011, in order to cover their 2010 NOX annual compliance position. In January 2011, Dover was allocated 1,988 SO2 allowances, 42 NOX seasonal allowances, and 76 NOX annual allowances. Dover has the appropriate number of allowances were set aside for retirement (see Exhibit 1).

(2) Per the Clean Air Interstate Rule, in 2009, NOx emissions will be governed by a seasonal and annual program. The NOx seasonal emissions pertain only to emissions (May 1 – Sep 30), similar to the previous trading regimen. Annual emissions cover the entire year. 19

(3) CAIR allowances are retired at a rate of 2 allowances for each ton emitted. Pre-CAIR allowances retain a 1 allowance to 1 ton value for compliance. It is assumed that pre-CAIR allowances will be retired before CAIR allowances. Given current dispatch expectations, the market value of the remaining 2007-2011 Dover allowance inventory is approximately $36,848.75 at the time of this report. This represents 3,189 pre-CAIR SO2 allowances trading at $3.75/ton, 3976 post-CAIR SO2 allowances trading at $2.50/ton, 72 NOx annual allowances trading at $195/ton, and 52 NOx seasonal allowances trading at $17.50/ton. SO2 Existing SO2 allowances continue to have little value as the market awaits the release of the final version of the Environmental Protection Agency’s (EPA) Clean Air Transport Rule (Transport Rule). See Figure 1 – SO2 Prices. With an ample bank of existing SO2 allowances in the market and the expectation that the final Transport Rule will require covered facilities to hold and retire SO2 compliance instruments issued under the new program, prices for current vintage or older allowances are expected to remain very low. Figure 1 – SO2 Prices since Last Monthly Report SO2 Allowance Prices (May / June) $5.00 $4.00 $3.00 $2.00 $1.00 $0.00 2009 (pre-CAIR) 2010/2011 (post-CAIR) NOx NOX annual allowance prices rebounded some in the wake of high temperatures in late May and early June (See Figure 2 – NOX Annual Prices since Last Monthly Report.) A hot 2010 summer helped push NOX annual prices near $550/ton. A similarly hot summer this year could place some upward pressure on NOX annual pricing. With that said, as with SO2 allowances, if the Transport Rule implements as expected in 2012, NOX allowances will have no value beyond meeting 2011 compliance requirements. With no incentive to bank allowances, it is unlikely that 20

NOX annual allowances will increase much above current levels, unless generators have vastly underestimated their compliance needs for 2011. NOX seasonal allowances lost some value over last month. Allowances continue to trade in low volumes and around $20/ton (See Figure 3 – NOX 2011.) As with NOX annual and SO2 allowances, new trading rules under the Transport Rule are unlikely to allow current vintage NOX seasonal allowances to qualify for compliance. Figure 2 – NOX Annual Prices since Last Monthly Report NOX Annual Allowance Prices (May / June) $300.00 $250.00 $200.00 $150.00 $100.00 $50.00 $0.00 Figure 3 – NOX Annual Prices since Last Monthly Report NOX Seasonal Allowance Prices (May / June) $20.50 $20.00 $19.50 $19.00 $18.50 $18.00 $17.50 $17.00 $16.50 $16.00 21

SO2 and NOx Outlook The final Transport Rule, setting new emissions trading rules, is expected to be released in June or July and implemented in January 2012. The expectation is that there will be new allowances for SO2 and NOX emissions, leaving little value for the existing bank of allowances beyond this year’s compliance requirements. It is difficult to estimate what the future compliance costs for SO2 and NOX emissions will be under new trading rules with a number of variables still unknown - the release of the final Transport Rule should provide some clarity. Senator Tom Carper (D-Delaware), one of the key proponents of a “legislative fix” to the SO2 and NOX market rules, announced this month that he will not pursue passing a multi-pollutant in this Congress. While there remain some proposals in the House of Representatives to delay EPA implementation of various air pollution rules, expectation is that legislation impacting these markets will not be enacted this year or next. With that, EPA’s Transport Rule will likely be the regulatory mechanism moving forward, although there remains the possibility that lawsuits filed after the final rule is released could delay implementation. RGGI and Federal Carbon Outlook RGGI allowance prices continue to price at very low levels, as the market is substantially over supplied, forcing prices to levels at or near the statutory price floor (see Figure 4 – RGGI Allowance Prices). Figure 4 – RGGI Allowance Prices since Last Monthly Report RGGI Prices (May / June) $1.95 $1.90 $1.85 $1.80 The big news in RGGI has been the announcement from New Jersey Governor Chris Christie that the state will withdraw from RGGI at the end of this year. The announcement is not expected to have an enormous impact on the market, but could be an impetus for other states to 22

follow suit. Although currently there are no expectations of other states exiting the program as New Hampshire, Delaware, and Maine have all recently voted down similar efforts to withdraw from RGGI and New York, Maryland, and Massachusetts, the three largest members in terms of emissions, remain committed to the program. RGGI program administrators are meeting to review program rules as part of their 2012 Comprehensive Review process. With the program over allocated, the major issue is whether anything can be done to lower the cap or limit the amount the existing bank can qualify for compliance. If the program continues with the existing planned caps and banked allowances are permitted for compliance at full value, RGGI allowances are likely to remain near current levels for the next several years. In Congress, there has been little movement or discussion on climate legislation nor is any expected through 2012. EPA will remain the primary driver at the federal level, although has recently announced that they will delay the release of proposed GHG emission limits for power plants, which were originally scheduled to be released this July. Proposed rules are now expected in September, although EPA maintains that final rules will be released in May 2012, as scheduled. 23

4.0 – OPERATIONS MANAGEMENT Management Highlights  During the month of May, there were no restricted work days or lost time accidents. The facility has now gone 229 days without an OSHA recordable accident or a lost time reportable accident. Three Near Misses were recorded for the month.  The plant received no Notice of Violations (NOVs). There was one environmental deviation on the amount of dissolved solids (TDS) going to the outfall. There were three opacity deviations that resulted from testing the updated controls while combusting #2 fuel oil on Unit 1.  The Units 1, 2, and 3 planned outages were cleared on Monday May 23 at 0600 hours.  Unit 11 was dispatched by PJM on May 30 but then the dispatch was cancelled later by PJM. The unit was dispatched on the following day and ran for 8.216 hours. Unit 3 was dispatched on May 31and ran for 13.750 hours. Units 1 and 2 were available but never dispatched.  On May 18, the modifications to the Unit 3 Burner Management System were tested and eventually the test was successful and the system deemed operational.  On May 17th, Erik Petty received a NAES Service Recognition Award from Vincent Scire, Plant Manager, in recognition of completing 10 years of service working at the City of Dover Generating Facilities.  The following is the NAES Monthly Report as submitted to PGAM. 24

1.0 Environmental, Health and Safety: During the month of May, there were no restricted work days or lost time accidents. The facility has now gone 229 days without an OSHA recordable accident or a lost time reportable accident. Three Near Misses were recorded for the month. 1) A LO/TO procedure to replace a valve on the caustic system in the VanSant DI was not effectively isolated due to water pressure still remaining on the line as the valve was in the process of being removed. 2) Upon startup, Unit 3 experienced low vacuum. An immediate investigation found that the exhaust hood cover plate was not completely tightened. 3) Scaffold erected to gain access to the Unit 3 expansion joint and ductwork combusted due to exposure to heat emitting from the air heater top guide bearing area during a unit dispatch. Wood planking had been installed directly over the air heater which then got hot and began to smolder. The flames were put out with an extinguisher and the planking was removed. The plant received no Notice of Violations (NOVs). There was one environmental deviation on the amount of dissolved solids (TDS) going to the outfall. There were three opacity deviations that resulted from testing the updated controls while combusting #2 fuel oil on Unit 1.

The implementation of the data substitution rules were caused by performing a linearity test outside the grace period. NAES ESS was able to provide assistance in reducing the NOx emissions from 137 tons to 119 tons since the October report. A petition to the EPA was sent out in February that would result in a reduction in reported emissions. The EPA has given preliminary approval to the petition request although it is not official until the plant receives a signed EPA approval. Until the issue is resolved, the EPA has locked the annual account and no allowances will be deducted until that time. Note# - 53 tons were purchased to help compensate for the shortage in seasonal NOx allowances. Note## - 22 tons were purchased to help compensate for the shortage in annual NOx allowances. Note###- 2 tons were reallocated by the EPA to the McKee Run 2011 account.

The actual expenses for May were $445,311 for an unfavorable variance of $17,203 or ≈ 4.02%. The variance was due to the following: PERSONNEL EXPENSES – Lower straight labor, overtime, and labor burdens accounted for a favorable variance of $15,100. MATERIALS AND SUPPLIES EXPENSES- Lower than budgeted expenses in Medical Supplies, Water Treatment Chemicals, Computer Hardware, and City Building Maintenance contributed to realizing a favorable variance of $14,378. ADMINISTRATIVE EXPENSES – Higher than budgeted expenses in the areas of Electric (due to billing cycle – both April and May booked in May), Training / Conference / Food, Environmental Expenses, Home Office Labor, Other Equipment /Maintenance , Radio Repairs - Maintenance, and Combustion Turbine Maintenance costs which contributed to an unfavorable variance of $46,681. The majority of the unfavorable variance was due to Electric billing ($43,000 of the $46,681 variance) The current budget forecast for the current fiscal year is $6,156,900 expensed versus an adjusted budget of $6,163,315 thereby realizing a 99.90%.expense rate. 30

6.0 General Plant Information Training: CEMS training was completed at VanSant for the Operations staff to allow checks to be completed on a daily basis by operators. VanSant is a remote site that is three miles away from McKee Run. Completing the daily checks by operators will provide consistency in work tasks and aid in ensuring tasks are completed in a timely manner. Training of all plant employees was held in May to educate them on being able to recognize Arc Flash Levels as well as identifying the applicable PPE to ensure their personal safety and the safety of others who may be in the arc flash exposure area. Subsequent to the training, the plant’s uniform policy has been revised to reflect the new safety standards. Plant employees continue General Physics safety training and environmental courses to enhance their overall knowledge of permit and safety requirements. As the GPI courses are being completed the employee reviews the standard operating procedure (SMP) for the same topic they are training on to review NAES policy as well. Used Oil training was conducted to familiarize employees with a plan revision and subsequent operational changes. Personnel: On May 13th, Erik Petty successfully passed the PJM System Operator Certification exam. Mr. Petty received a shirt to commemorate his achievement for passing the PJM Operator exam. On May 17th, Erik Petty received a NAES Service Recognition Award from Vincent Scire, Plant Manager, in recognition of completing 10 years of service working at the City of Dover Generating Facilities. 38

III. GLOSSARY Energy Only Unit Cost ("EOU") accounts for the wholesale energy costs excluding capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. The AIE includes the costs from settling the hedged or forward transactions; the energy bought on the ISO (Independent System Operator or PJM) day-ahead to cover the open position (un-hedged); load following costs associated with balancing the actual load in the ISO real-time market; energy management service related fees; the ISO transmission charges and credits to load serving entities; the ISO ancillary services charges such as generation regulation, spinning reserve, and reactive power; and the ISO administrative charges and cost of service recovery fees. All In Cost of Service ("AICS") accounts for the net cost of wholesale power to the City of Dover Electric Utility. The AICS starts with the AIE and adds the costs or credits from capacity obligations, capacity credits for Dover-owned generation, generation revenues, generating plant costs, the black start ancillary services credit for the Van Sant plant, and revenues associated with the sale of emission allowances. Black Start is a generating ancillary service that is the process of restoring a generating plant to service without the support of an external power supply to power auxiliary equipment needed for start up operations. Capacity UCAP Obligated Purchased is the obligation and payment by all load serving entities in PJM including Dover for the Unforced Capacity (UCAP) requirement from PJM that satisfies the PJM reserve requirements. Generation Capacity Credit: is the credit provided to generators for supply capacity to the system. The price is determined by the PJM Reliability Pricing Market auction process that includes three auctions for each capacity year. Generation Production Margin accounts for the variable margin excluding variable O&M and emissions. The Generation Production Margin is calculated by taking the PJM revenues credited to the plant including any balancing charges or credits less the fuel costs. Generation Production Margin includes both “Economic and reliability dispatch” and “Testing.” Economic and reliability dispatch equals the margin achieved when Dover’s generating plants are dispatched by PJM for either economic dispatch (the system energy price is greater than the Dover bid price) or reliability dispatch whereby PJM pays the generating cost of the plants for the hours the plant is run to support the system. Generation Testing equals the Generation Production Margin associated with testing. This is usually expected to be a negative margin because the plant is potentially being dispatched / run when energy prices do not cover its costs. Non-Production Revenue equals the credits from PJM to Dover for Generation Capacity Credit, the Black Start Revenue and the sales by Dover of Emission Allowances. 42

ACTION FORM PROCEEDING Utility Committee DEPARTMENT OF ORIGIN: City Manager’s Office DATE SUBMITTED: July 28, 2011 PREPARED BY: Ann Marie Townshend, AICP, Director of Planning & Community Development on behalf of Scott D. Koenig, P.E., Interim City Manager SUBJECT: Proposed ordinance to prohibit new private shallow wells within the City limits and to clarify that wells for geothermal heating and cooling systems are permitted in accordance with certain criteria. REFERENCE: Dover Code, Chapter 110 – Utilities, Article III – Water Service, Division 1 – Generally, Section 110-67 – Private Wells RELATED PROJECT: N/A REVIEWED BY: Scott D. Koenig, P.E., Interim City Manager; Ron Lunt, Public Utilities Director EXHIBITS: Draft Ordinance #2011-20 EXPENDITURE REQUIRED: N/A AMOUNT BUDGETED:N/A FUNDING SOURCE (Dept./Page in CIP & Budget): N/A TIME TIMETABLE: RECOMMENDED ACTION: Staff recommends that the Committee forward the proposed ordinance to City Council for first reading on August 22, 2011 and final reading and City Council Action on September 12, 2011. BACKGROUND AND ANALYSIS The proposed ordinance would prohibit new private shallow wells within the City of Dover. This prohibition will protect the water resources of the unconfined aquifer from which the City draws a portion of its water supply, as well as protect the City’s Certificate of Public Convenience & Necessity (CPCN). Currently, private shallow wells, for irrigation purposes in particular, are permitted in accordance with certain criteria specified in the ordinance. Additionally, geothermal technology for heating and cooling is an emerging technology that was not contemplated when this section of the code was implemented. Geothermal systems require well permits from DNREC, although they do not draw water from the ground. The proposed ordinance would clarify that wells associated with the installation of closed loop geothermal systems are permitted within the City of Dover in accordance with specified criteria.

CITY OF DOVER PROPOSED ORDINANCE #2011-20 1 BE IT ORDAINED BY THE MAYOR AND COUNCIL OF THE CITY OF DOVER, IN COUNCIL 2 MET: 3 That Chapter 110 - Utilities, Article III - Water Service, Division 1 - Generally, Section 110-67 - Private 4 Wells, be amended by deleting text indicated in red strikeout (subsection (b) Shallow wells in its entirety) 5 and inserting text indicated in bold, blue, italics as follows: 6 Sec. 110-67. Private wells. 7 (a) When authorized.
