**I. INTRODUCTION**

This document presents the Fugitive Dust Suppression and Monitoring Plan
for the LNG Terminal and the Pipeline of the AES Sparrows Point LNG, LLC
(Sparrows Point LNG) Project. AES proposes to construct, own, and
operate a new liquefied natural gas (LNG) import, storage, and
regasification terminal (LNG Terminal) at the Sparrows Point Industrial
Complex situated on the Sparrows Point peninsula east of the Port of
Baltimore in Maryland. LNG will be delivered to the LNG Terminal via
marine vessel, offloaded from the marine vessel to shoreside storage
tanks, re-gasified on the LNG Terminal site (Terminal Site), and
transported to consumers via pipeline. Regasified natural gas will be
delivered to markets in the Mid-Atlantic Region and northern portions of
the South Atlantic Region through an approximately 88-mile, 30-inch
outside diameter natural gas pipeline (Pipeline) to be constructed and
operated by Mid-Atlantic Express, LLC (Mid-Atlantic Express). The
Pipeline will extend from the LNG Terminal to interconnections with
existing natural gas pipeline systems near Eagle, Pennsylvania.
Together, the LNG Terminal and Pipeline projects are referred to as the
Sparrows Point Project or Project. Both Sparrows Point LNG and
Mid-Atlantic Express (hereinafter collectively referred to as AES) are
subsidiaries of The AES Corporation.

The intent of this Fugitive Dust Suppression and Monitoring Plan (Plan)
is to avoid or minimize potential impacts associated with construction
at the LNG Terminal and Pipeline.

2.  **PHYSICAL DESCRIPTION**

The primary areas of construction where dust generating areas are
present include the LNG Terminal, the Pipeline and the above ground
facilities. The aboveground facilities proposed for the Pipeline include
a pressure reduction facility (including metering and regulation
equipment) located at the LNG Terminal, an estimated nine mainline valve
facilities for the Pipeline, and three interconnection tie-in locations
with the Columbia, Transco, and TETCO systems.

The LNG Terminal will be located on an approximately 45-acre upland
parcel within the existing Sparrows Point Industrial Complex (Sparrows
Point) located in Baltimore County, Maryland as shown on Figure 1.3-2
(Sheet 2). The LNG Terminal will make use of an existing pier located at
the northern end of the Terminal Site. The existing pier will be
modified to accommodate mooring of LNG ships. The modifications will
consist of repairing existing piles, resurfacing the deck, and building
an unloading platform and pipe trestle on top of the pier. Assuming
receipt of all required regulatory approvals and permits, the LNG
Terminal construction is planned to commence in 2008, and is expected to
be completed in the fourth quarter of 2010.

In addition to the Terminal Site an additional 35 acres of upland area
on Sparrows Point will be utilized for the Dredged Material Recycling
Facility (DMRF) as shown on Figure1C-3. A description of the DMRF, along
with details regarding the materials management and storage, is located
in Resource Report 1, *General Project Description --* Appendix 1C.

The Pipeline consists of approximately 88-miles of 30-inch outside
diameter natural gas pipeline and associated facilities (e.g., mainline
valve sites, interconnect metering facilities, monitoring controls, and
leak detection) which will extend from the LNG Terminal in Sparrows
Point, Maryland to a terminus near Eagle, Pennsylvania. The Pipeline
will be installed within a 50-foot-wide permanent ROW. During
construction in non-agricultural lands, 25 feet of additional temporary
space will be required (in aggregate, a 75-foot construction
right-of-way, or CROW) to allow crews to safely construct all Pipeline
facilities. In areas where additional working width is necessary (e.g.,
to stockpile topsoil in agricultural lands), the CROW may be expanded up
to an additional 25 feet to accommodate the need (thus comprising a
100-foot CROW). Temporary construction land requirements for the
Pipeline facilities are approximately 1,603 acres. Permanent operational
land requirements for the Pipeline facilities are estimated to be
approximately 545 acres, including permanent ROW and access roads known
to date. Assuming receipt of all required regulatory approvals and
permits, Pipeline construction is planned to commence in early 2009, and
to be completed in 2010.

**3.0 DUST SUPPRESSION AND CONTROLS**

The critical dust generating areas are anticipated to be the excavation
trenches, the soil and Process Dredge Material (PDM) stockpiles, loading
and discharge of the material handling equipment, and the placement of
the soils in the material management areas. In addition, the potential
of dust generation exists during any transportation of soil.

**[Monitoring Procedures]{.underline}**

The Environmental Inspector will monitor critical dust generating areas
for dust, complete visual inspections of these areas and oversee any
corrective actions for dust suppression procedures. The Environmental
Inspector will also address and evaluate public concern and complaints
about dust suppression, and provide input on engineering controls to
mitigate fugitive dust concerns. Construction personnel will review this
Plan prior to working on sites.

**[Engineering Controls]{.underline}**

Based upon visual observation, the need for dust suppression procedures
will be determined by the Environmental Inspector. The guidance for dust
control procedures are 25 Pennsylvania Code §123.1(C)(1-4) and COMAR
26.11.06.03D.

Based on this guidance the following techniques may be employed to
mitigate the generation and migration of fugitive dust during
construction:

-   applying water on the right-of-ways, stockpiles, trenches, and other
    surfaces which may give rise to airborne dust;

-   spraying water on temporary roads at the end of the work shift to
    form a thin crust;

-   misting equipment and excavation faces;

-   spraying water on buckets during excavation and dumping;

-   watering of any visibly dry disturbed soil surface areas of
    operation;

-   covering, when in motion, open-bodied vehicles transporting
    materials likely to crease air pollution;

-   restricting vehicle traffic to \<15 MPH; and

-   reducing the size of any open excavation.

If the dust suppression techniques do not lower visual observations, the
specific task generating the fugitive dust may be suspended until
appropriate corrective measures are identified and implemented to remedy
the situation.

**[Administrative Controls]{.underline}**

The Environmental Inspector will determine when there is a need for dust
suppression procedures. In addition to tasks outlined in the
Environmental Controls Plan, the Environmental Inspector will:

-   ensure compliance with recommended mitigative measures;

-   identify, document, and monitor corrective actions;

-   document and track any complaints;

-   advise the Chief Construction Inspector when conditions make it
    advisable to restrict construction activities; and

-   keep records of compliance with the environmental conditions and
    mitigative measures.

Complaints from the public or municipalities concerning dust suppression
will be addressed and evaluated by the Environmental Inspector. In the
event of a complaint, the Environmental Inspector will promptly
investigate the complaint, determine appropriate mitigative measures,
and the source of the complaint will be notified of the resolution.
