Introductions/Welcome/Contact Information
Two new members were introduced and welcomed to the CAB. Mr. Anthony deFiore,
appointed by New Castle County President, Chris Bullock and Leonard Sophrin appointed by
Wilmington Mayor’s Office, Mayor Dennis Williams.
As CAB Vice Chairman, Mr. Thomas Noyes announced himself as Acting Chairman for the

Department of Natural Resources and Environmental Control (DNREC) update
Mr. Hartman presented DNREC’s update on their activities at Cherry Island Landfill (see
Mr. Hartman reported two (2) odor complaints concerning Cherry Island Landfill (CIL)
described as a ‘trash odor’. Both complaints were received by DNREC on January 29, one
on Pyles Lane and the other on Harrisburg Avenue. Mr. Hartman noted that the complaints
were not verified. Mr. Hartman mentioned that the odors could have been from Wilmington
Organics Recycling Center (WORC), considering that there have been recent odor
complaints about that facility.
Ms. Roddy explained that there are two (2) potential sources of odors from the landfill, the
actual waste and the landfill gas (lfg) that is generated as the waste decomposes. Odors

traveling off site from active waste placement are not likely. She further explained that the
best method of controlling lfg odors is through an efficient lfg collection system. Ms. Roddy
explained that the Cherry Island lfg system collects gas efficiently through an extraction
system and currently, the lfg is either piped to Croda (at Atlas Point) for combined heat and
power generation or managed by burning the lfg with flares.
Mr. Hartman also reported that two (2) fires occurred at CIL since the last meeting. On
January 23 DSWA reported that smoke was observed coming out of a lfg flare stack. DSWA
called 911 and the Wilmington Fire Department responded. Flare A suffered damage and is
currently not operational until its repairs are complete. Flare B is currently in use.
Ms. Marconi explained that it is possible that odors could potentially occur if Flare B goes out
of service; however, she is working with Croda to accept as much gas as possible and is
prepared to rent a temporary flare if necessary. She informed the CAB that Flare A should
be repaired by mid-May.
Mr. Hartman reported that the 2nd fire occurred on January 28 while cutting grass. The fire
was extinguished with water and soil. No damages or injuries occurred.
Mr. Hartman reported that the current CIL operating permit, SW-06/01, is in the process of
being modified. The DRAFT modification to the permit reduces the CAB meeting frequency
from four (4) times per year to three (3) times per year, as requested by the CAB. The
modification also eliminates the requirement for the CAB members to live within 5 miles of the
landfill. The DRAFT modification also includes other changes such as increased stormwater
monitoring frequency and modifications to the geotechnical monitoring plan.
DNREC has received three (3) requests for a hearing regarding these modifications. DNREC
is in the process of scheduling the hearing.
Mr. Sophrin asked who proposed the changes in the meeting frequency and asked the
reason for the residency requirement change.
Mr. Noyes reported that the CAB proposed the meeting frequency change and voted on it.
Mr. Parkowski explained that the CAB requested the proposed changes, not DSWA. Mr.
Parkowski also stated that the CAB Charter was adopted by the original CAB and does not
match the permit regarding the residency requirement. The Charter states that the members
shall be residents of New Castle County living above the Chesapeake and Delaware Canal.
The CAB further discussed the CAB meeting frequency and residency requirement.
Mr. D’Anna informed the new CAB members that the primary reason for the meeting
frequency modification was due to the lack of attendance and inability to have a quorum at
the meetings. He also expressed the fact that the CAB had already discussed many CIL

issues at length, and felt that four (4) meetings per year were not necessary at this point
because there were not any problems with CIL.
Ms. Marker explained the public hearing process. Mr. Hartman then explained that he had
attempted to contact the citizens that requested the hearing, by telephone and by email, to
discuss the proposed permit changes with them
Mr. D’Anna inquired about recent violations at the WORC facility.
Ms. Marker responded that enforcement action was recently taken. She stated that one of
the violations was related to the amount of material that was stored on site.
Mr. Sophrin inquired about the Delaware Recyclable Products Inc. (DRPI) facility and their
permit requirements, specifically their height restrictions, as compared to CIL.
Ms. Marker responded that the DRPI’s Permit is different and explained that they are a
private construction and demolition debris (C&D) landfill. Ms. Marker further explained that
the DRPI does have an operating permit and limitations to their cell growth. She indicated
that she would review their permit conditions and confirm the height limitation.
Mr. Sophrin asked how much of the waste going to the DRPI would come to CIL if the DRPI
did not exist.
Mr. Parkowski estimated that approximately 25,000 tons of waste could potentially come to
CIL if the DRPI did not exist.
The CAB inquired about DSWA’s bond rating.
Mr. Watson explained that Moody’s bond rating was and continues to be A2, but just recently
has been given a negative outlook. Mr. Watson further explained to the CAB that the
negative outlook was based upon a decreasing amount of excess net revenue due to a
decreasing amount of tons of waste received. DSWA expects to continue to perform higher
than budgeted (debt coverage ratio) into the future.
CIL Update
DSWA LFG Generation
Ms. Roddy explained that CIL is currently generating approximately 4,000 scfm of lfg. The lfg
is currently transmitted to Croda in New Castle, DE for combined heat and power. CIL’s
renewable energy Contractor is Cummins. Cummins will likely have multiple end users for
the lfg in the future, including the City of Wilmington (COW). The COW will use CIL lfg in their
future sludge drying process.

Ms. Roddy explained that DSWA’s two (2) other landfills have renewable energy projects and
use lfg to generate electricity. These projects are operated by Ameresco. Ms. Roddy
distributed a summary sheet detailing lfg collection and renewable energy conversions for
DSWA’s three (3) landfills.
Mr. Sophrin asked if both Cummins and Ameresco are selling the renewable energy credits
themselves and how much lfg is being beneficially used.
Ms. Roddy confirmed that Cummins and Ameresco are selling the renewable energy credits
themselves and explained that approximately 80% of the lfg collected is being beneficially
Landfill Capacity
Ms. Roddy explained that CIL opened in 1985. DSWA recently constructed a landfill
expansion that provides 40,000,000 cubic yards of additional landfill capacity. The CIL
volume consumption rate for the previous 24 months was 500,000 cubic yards per year,
which includes both waste and cover. Therefore, the remaining life is approximately 80
Mr. Sophrin inquired about the waste composition at CIL.
Mr. Parkowski explained that DSWA has a very detailed waste characterization report that
represents four (4) seasons and involved hand-sorting and weighing over fifty (50) different
categories of waste materials. DSWA uses this report as a planning tool and will provide a
copy to the CAB.
Permit Modification
The CAB discussed the pending permit modification and the proposed modifications to the
CAB meeting frequency and residency requirements. Members also discussed the original
CAB charter and its potential conflict with the Permit.
Mr. Sophrin expressed his interest in becoming more familiar with the proposed Permit
modifications prior to the Public Hearing.
Mr. D’Anna then made a motion to remain with the original Permit language to hold four (4)
meetings per year. The motion was second by Mr. Sophrin and unanimously approved by
the CAB.
Mr. Noyes asked if anyone was interested in making a motion to change the Charter to
conclude a 5 mile provision. There was no response, so Mr. Noyes announced that the
Charter stands.

5:00 p.m. Location of meeting to be determined.
Meeting adjourned at approximately 7:15 p.m.
DSWA Cherry Island Landfill Summary for the Citizens Advisory Board
Prepared by Robert Hartman, DNREC Solid & Hazardous Waste Management Section
April 15, 2013
1. During the 4
th quarter of 2012, there were no odor complaints received by the DNREC
concerning the DSWA Cherry Island Landfill (CIL). The DNREC logged only two odor
complaints for the CIL during all of 2012. During the 1st quarter of 2013, there were two
odor complaints received, both on January 29th
. Both callers (one on Pyles Lane and one on
Harrisburg Ave) reported a trash odor, and believed that to be coming from the CIL.
2. In February 2013, DNREC completed the initial review of the construction quality assurance
report for the completed landfill expansion project and provided comments to the DSWA.
The report is intended to certify that the landfill expansion was constructed in accordance
with the permit requirements.
3. There were no fires reported at the CIL during the 4
th quarter of 2012; however, there were
two fires reported at CIL during the 1st quarter of 2013.
a. DSWA shut-down Flare A on January 23, 2013 after smoke was observed coming out
of the landfill gas flare stack. Staff contacted 911 and the Wilmington Fire
Department responded. Subsequent investigation revealed that the flame arrestor had
functioned as designed to contain the fire within the landfill gas flare system. Flare A
suffered damage to the landfill gas intake line and to the fiberglass mixing chamber.
DSWA is working to repair the damaged flare, and is relying on Flare B until that
repair is completed.
b. On March 28, 2013, DSWA reported smoke coming from grass cutting activity on
Phase 2 of the landfill. The fire was contained within a small area around the tractor
mower on an inactive, vegetated portion of the landfill. The fire did not involve
landfill waste. DSWA operations staff responded to the fire, smothering it with soil
and hosing the area down with water. There were no damages reported.
4. There were no prohibited wastes reported as received at the landfill during the preceding two
quarters (4th 2012 and 1st 2013).
5. Since the previous CIL Summary for the CAB, DNREC staff continued to inspect the facility
and 12th Street for odor, litter and dust. According to our on-site inspections, DSWA has
been controlling odor, litter and dust both on site and off in accordance with the conditions of
their solid waste facility permit.
6. DSWA remains in compliance with the conditions of the Yard Waste Ban.
7. The Solid & Hazardous Waste Management Section has drafted a proposed modification to
Permit SW-00/01. The draft modification includes the change to CAB meeting frequency,
requested by the CIL Citizens Advisory Board. The draft modification also relaxes the
requirement for CAB members to live within five miles of the CIL. The SHWMS provided
public notice of this proposed modification on February 13th and received three requests from
the public for a hearing. We are in the process of scheduling that hearing.
Note Added 4/16/13: Regarding item 1 above, in December 2012, there was one odor complaint
called-in directly to DSWA from Salem County NJ. The DSWA investigated and found no CIL
odors off-site after receiving the complaint. That complaint raises the total number of CIL odor
complaints during 2012 to three.
