ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

      At the annual meeting of stockholders (the "Annual Meeting") held on
September 15, 2006, the stockholders of WCA Waste Corporation ("WCA") approved,
among other things, the Second Amended and Restated 2004 WCA Waste Corporation
Incentive Plan (the "Amended Plan"). The Amended Plan was previously approved by
the board of directors of WCA (the "Board") on August 17, 2006, subject to
stockholder approval. The Amended Plan increases the number of shares of common
stock, par value $0.01 per share ("Common Stock"), of WCA available for award
grants by an additional 750,000 shares, from 1,500,000 to 2,250,000. Other than
the aforementioned change, the Amended Plan is identical to the prior plan.

      A discussion of the material terms of the Amended Plan is included on
pages 39 to 51 of WCA's definitive proxy statement on Schedule 14A filed with
the Securities and Exchange Commission ("SEC") on August 25, 2006 under the
heading "Proposal 3: Approval of Amendment and Restatement of the Amended and
Restated 2004 WCA Waste Corporation Incentive Plan." A copy of the Amended Plan
is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

ITEM 3.01  NOTICE OF DELISTING OR FAILURE TO SATISFY A CONTINUED LISTING RULE OR
           STANDARD; TRANSFER OF LISTING.

      Please read the discussion under Item 5.02 below, which is incorporated
herein by reference.

ITEM 5.02  DEPARTURE OF DIRECTORS OR PRINCIPAL OFFICERS; ELECTION OF DIRECTORS;
           APPOINTMENT OF PRINCIPAL OFFICERS.

      Immediately after the Annual Meeting on September 15, 2006, Ares Corporate
Opportunities Fund II, L.P. ("Ares") elected Mr. Antony P. Ressler and Mr.
Jeffrey S. Serota to serve as members of the Board. Ares, as the sole owner of
WCA's Series A Convertible Pay-In-Kind Preferred Stock, par value $0.01 per
share ("Preferred Stock"), is entitled to elect members to the Board voting as
separate class as follows: (i) two directors to the Board for so long as Ares
continues to hold Preferred Stock representing at least 20% of "post-conversion
equity" (outstanding Common Stock assuming conversions into common shares of all
securities, including the Preferred Stock and assuming Preferred Stock dividends
accelerated to include a full five years); (ii) one director for so long as it
continues to hold at least 10% of post-conversion equity; and (iii) no directors
below 10%. Messrs. Ressler and Serota will serve a one-year term or until their
successors are duly elected and qualified or until their earlier death,
resignation or removal. Messrs. Ressler or Serota are entitled to be observers
to committees of the Board by virtue of the terms of the transaction agreements
signed in connection with the issuance of the Preferred Stock.

      Messrs. Ressler and Serota are employed by affiliates of Ares and Ares and
certain of its affiliates have been party to various transactions or agreements
with WCA as described under the heading "Certain Relationships and Related
Transactions" beginning on page 13 of WCA's definitive proxy statement on
Schedule 14A filed with the SEC on August 25, 2006.

      On September 15, 2006, WCA provided notice to the Nasdaq Global Market
("Nasdaq") that after the election of Messrs. Ressler and Serota by Ares WCA no
longer satisfies the independent director requirements for continued listing on
Nasdaq under Marketplace Rule 4350(c)(1), which requires WCA to maintain a
majority of independent directors on its Board. As a result of the election of
Messrs. Ressler and Serota by Ares, the number of WCA's directors who are deemed
"independent" under Nasdaq listing standards is now three of seven total
directors. In the notice, WCA outlined its plan pursuant to Nasdaq Marketplace
Rule 4350(c)(1) to be in compliance with Rule 4350(c)(1) within the grace period
therein prescribed (namely the earlier of its next annual shareholders meeting
or one year from the occurrence of the appointment).
