Update: CSAPR Cross State Air Pollution Rule

CSAPR attempts to regulate “upwind” states to prevent areas in “downwind” states from exceeding air quality standards for fine particulate matter (PM 2.5) and ozone.

US Court of Appeals issued a “stay” on December 30, 2011, finding that petitioners were likely to succeed on the merits and that there is the possibility of irreparable injury.

Decision expected as early as July of 2012.

23

Update: MATS Rule Mercury and Air Toxics Standards

Percent of Mercury Deposition that Originates from Outside the United States

Finalized December 16, 2011.

Aims to “reduce emissions” of mercury and other hazardous air pollutants (HAPs).

Most expensive rule EPA has ever written for power plants.

Cost of the rule exceeds the health benefits from HAPs reduction by a factor of 1,600 to 1.

24 States sued the EPA challenging the merits of the rule.

24

Combined Pain as Result of CSAPR and MATS

183,000 jobs destroyed per year(a).

$170 billion in increased energy prices(a).

57 announced plant closures representing 25 GW of capacity (b).

New in 2012: New Source Performance Standards (NSPS) for GHGs

After the defeat of cap and trade legislation, this is the Obama EPA’s attempt to implement a backdoor global warming emissions scheme.

RequiresRe quires a maximum CO2 emissions rate of 1,000 pounds per megawatt-hour a rate that new coal-fired power plants cannot meet without installing carbon capture and sequestration (CCS) technology.

Due to the infeasibility of CCS, NSPS in effect prohibits new construction of commercial scale coal-fired power plants.

Gas Overview

J.P.Morgan – North America Equity Research:

• E&P research team expects gas to reach $4/Mcf by November 2012. Analyst The key reasons are:

1. There are fewer gas rigs running. Gas production from 1 gas rig equals ~2 liquids rich gas rigs (based on Chesapeake Data). With lower productivity in Haynesville and Marcellus better gas production discipline could be expected.

2. US E&P gas production growth is slowing down.

3. Gas was at $3.50/Mcf in Nov ‘11 but is now sub $2 level because of the unprecedented surplus due to combined effects of a warm winter and production growth – the surplus needs to be pulled down by November.

Rig Counts: as of 4/12/12

Note:: EBITDA is defined as income before net interest expense, income taxes and depreciation, depletion and amortization. Management believes EBITDA is a useful indicator of its ability to meet debt service and capital expenditure requirements and uses EBITDA as a measure of operating performance. EBITDA should not be considered as an alternative to net income, income from operations, cash flows from operating activities or any other measure of financial performance presented in accordance with generally accepted accounting principles. EBITDA is not intended to represent cash flow and does not represent the measure of cash available for distribution. The Partnership’s method of computing EBITDA may not be the same method used to compute similar measures reported by other companies, or EBITDA may be computed differently by the Partnership in different contexts (e.g. public reporting versus computation under financing agreements).
