Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of the Partnership have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and in compliance with the instructions to Form 10-Q and Article 10 of Regulation S-X, neither of which requires all of the information and footnotes required by GAAP. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC, and accordingly, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Partnership’s Form 10-K for the year ended December 31, 2017 filed with the SEC on March 5, 2018 (“Annual Report”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, consisting only of normal and recurring adjustments, considered necessary for a fair statement of the Partnership’s financial position as of March 31, 2018, and the consolidated results of operations and cash flows for the periods presented. The accompanying unaudited condensed consolidated financial statements include the accounts of the Partnership. All significant intercompany accounts and transactions have been eliminated in consolidation. Operating results for the three months ended March 31, 2018 are not necessarily indicative of the results that may be expected for the year ending December 31, 2018 or any other reporting period. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Accuracy of estimates is based on accuracy of information used. Significant items subject to such estimates and assumptions include the useful lives of property, plant, and equipment, the valuation of property, plant, and equipment, and other contingencies.
Recently Adopted and Recently Issued Accounting Standards	Recently Adopted and Recently Issued Accounting Standards The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification is the sole source of authoritative GAAP other than SEC issued rules and regulations that apply only to SEC registrants. The FASB issues Accounting Standards Updates (“ASU”) to communicate changes to the codification. The Partnership considers the applicability and impact of all ASU’s. The following are those ASU’s that are relevant to the Partnership. On August 29, 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 provides guidance on the cash flow reporting of certain issues that were either unclear or not addressed under existing U.S. GAAP. The standard requires the retrospective transition method and is effective for annual and interim periods in the fiscal years beginning after December 15, 2017, although early adoption is permitted. The adoption of ASU 2016-15 did not have any impact on the Partnership's consolidated financial statements or disclosures. On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which requires an entity to recognize the amount of revenue which it expects to be entitled for the transfer of promised goods or services to customers. It also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue, cash flows arising from customer contracts, including significant judgments and changes in judgments, and assets recognized from costs incurred to obtain or fulfill a contract. The adoption of ASU 2014-09 on January 1, 2018, using the modified retrospective approach, had no significant impact on our results of operations, cash flows or financial position. Revenue continues to be recognized at a point in time for our product sales when products are delivered to or picked up by the customer. No transition adjustment was necessary upon adoption. Additional information and disclosures required by this new standard are contained in note 3 – Significant Accounting Policies. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which supersedes Accounting Standards Codification (“ASC”) 840, Leases. Subsequent to the issuance of ASU 2016-02, ASC 842 was amended by various updates that amend and clarify the impact and implementation of the aforementioned update. These updates require lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. These updates also expand the required quantitative and qualitative disclosures surrounding leases. The new lease standard requirements are effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and early adoption is permitted. The Partnership has begun evaluating the new lease standard, including the review and implementation of the necessary changes to our existing process and systems that will be required to implement this new standard and the effect of adoption on our consolidated financial statements. We plan to adopt this ASU beginning on January 1, 2019 using the modified retrospective transition approach.
