Ladies and Gentlemen:

    We are acting as counsel to Georgia Gulf Corporation (the "Company"), a
corporation organized under the laws of the State of Delaware, and its
Subsidiary Guarantors (as defined below) in connection with (i) the offer to
exchange (the "Exchange Offer") $1,000 principal amount at maturity of the
Company's 10 3/8% Senior Subordinated Notes due 2007 (the "Exchange Notes") for
each $1,000 principal amount at maturity of Company's outstanding 10 3/8% Senior
Notes due 2007 (the "Private Notes" and, together with the Exchange Notes, the
"Notes") and (ii) the preparation of the prospectus (the "Prospectus") contained
in the registration statement on Form S-4 (the "Registration Statement")
(No. 333-34244) filed with the Securities and Exchange Commission by the Company
for the purpose of registering the Exchange Notes under the Securities Act of
1933 (the "Act"). The Private Notes have been, and the Exchange Notes will be
issued, pursuant to an Indenture, dated as of November 12, 1999 (the
"Indenture"), between the Company and SunTrust Bank, Atlanta as trustee. The
Notes are fully and unconditionally guaranteed (the "Guarantees") by each of
Georgia Gulf Chemicals & Vinyls, LLC, Georgia Gulf Lake Charles, LLC, North
America Plastics, LLC, GG Terminal Management Corporation, and Great River
Oil & Gas Corporation (the "Subsidiary Guarantors").

    We have examined originals or copies, certified or otherwise identified to
our satisfaction, of such corporate records, agreements, documents, and other
instruments and such certificates or comparable documents of public officials
and representatives of the Company and have made such other and further
investigations as we have deemed relevant and necessary as a basis for the
opinions hereinafter set forth. In such examination, we have assumed the
genuineness of all signatures, the legal capacity of natural persons, the
authenticity of all documents submitted to us as originals, the conformity to
original documents of all documents submitted to us as certified or photostatic
copies and the authenticity of the originals of such latter documents.

    Based on the foregoing and subject to the qualifications and limitations
stated herein, we are of the opinion that when the Exchange Notes, substantially
in the form as set forth in the Indenture filed as an exhibit to the
Registration Statement, have been duly executed by the Company and authenticated
by the trustee in accordance with the Indenture and duly delivered in exchange
for the Private Notes in accordance with the Exchange Offer in the manner
described in the Registration Statement, the Exchange Notes will constitute
valid and binding obligations of the Company and the Guarantees will constitute
valid and binding obligations of each Subsidiary Guarantor, except to the extent
such obligations may be limited by bankruptcy, insolvency fraudulent conveyance,
reorganization, moratorium and other similar laws relating to or affecting
creditors' rights generally and general equitable principles (whether considered
in a proceeding in equity or at law).

    We hereby consent to the use of our name under the caption "Legal Matters"
in the Prospectus forming part of the Registration Statement and to the filing
of this opinion as Exhibit 5 to the Registration Statement.

                                        Very truly yours,

                                        /s/ JONES, DAY, REAVIS & POGUE
