The Soda Ash segment's **49% equity interest** in Ciner Wyoming, a trona ore mining and soda ash production business, makes it one of the largest and lowest-cost producers globally[63](index=63&type=chunk)[64](index=64&type=chunk) - Ciner Wyoming is undertaking a significant capacity expansion project to increase production to **3.5 million tons/year**, which will be partly funded by reinvesting cash, leading to reduced distributions to partners (expected **$25 million to $28 million annually**) until the project is funded[74](index=74&type=chunk) - The company faces significant customer concentration, with Foresight Energy and its subsidiaries accounting for **$58.9 million** and Contura Energy for **$40.7 million** in total revenues in 2019[75](index=75&type=chunk) - Operations are subject to extensive federal, state, and local environmental, health, and safety regulations, including those related to air emissions (Clean Air Act, GHG emissions), water discharges (Clean Water Act), and mine safety[81](index=81&type=chunk)[82](index=82&type=chunk)[83](index=83&type=chunk)[85](index=85&type=chunk)[86](index=86&type=chunk)[87](index=87&type=chunk)[91](index=91&type=chunk)[95](index=95&type=chunk)[97](index=97&type=chunk) -

Cash distributions are not guaranteed and may fluctuate, with debt agreements and the partnership agreement restricting the ability to increase distributions[104](index=104&type=chunk)[105](index=105&type=chunk) - The company's significant leverage (**$524.1 million** total indebtedness as of December 31, 2019) and debt service obligations could adversely affect its financial condition and limit operational flexibility[107](index=107&type=chunk) - Prices for both metallurgical and thermal coal are volatile and depend on factors beyond the company's control, including supply/demand, regulations, and alternative fuels, with declines potentially leading to asset impairments[109](index=109&type=chunk)[112](index=112&type=chunk)[113](index=113&type=chunk)[114](index=114&type=chunk) - The company derives a large percentage of revenues from a small number of coal lessees (e.g., Foresight Energy, Contura Energy), making it vulnerable to interruptions in their ability to make royalty payments or to their bankruptcies and mine closures[115](index=115&type=chunk)[116](index=116&type=chunk) - Mining operations are subject to various operating risks (e.g., permitting delays, equipment failures, transportation disruptions, adverse weather, labor issues, safety incidents) that could result in lower revenues, while increased regulatory compliance costs, insurance, and permitting expenses also impact profitability[117](index=117&type=chunk)[119](index=119&type=chunk) - Climate change legislation and regulations, including those restricting greenhouse gas emissions, have led to and will continue to lead to changes in fuel consumption patterns by electric power generators, reducing coal demand and related revenues[120](index=120&type=chunk)[121](index=121&type=chunk)[122](index=122&type=chunk) - Concerns about environmental impacts also affect lending and investment policies, potentially limiting capital access and increasing insurance costs[120](index=120&type=chunk)[121](index=121&type=chunk)[122](index=122&type=chunk) - Prices for soda ash are volatile, directly affecting Ciner Wyoming's profitability, and high natural gas prices increase production costs, impacting competitiveness[126](index=126&type=chunk)[131](index=131&type=chunk) - The planned termination of ANSAC membership could adversely affect Ciner Wyoming's ability to compete internationally and increase sales costs[126](index=126&type=chunk)[131](index=131&type=chunk) - Significant delays or higher-than-expected costs associated with Ciner Wyoming's capacity expansion project could adversely affect its profitability and ability to make distributions, with the depletion of deca stockpiles by **2023** further impacting production rates without this expansion[132](index=132&type=chunk) - Unitholders have limited ability to remove the general partner due to high voting thresholds and substantial ownership by the general partner and preferred unitholders[143](index=143&type=chunk)[144](index=144&type=chunk) - The preferred units are senior in distributions and liquidation, and their conversion could result in substantial dilution of common unitholders' ownership interests[146](index=146&type=chunk)[147](index=147&type=chunk) - The company's tax treatment as a partnership for U.S. federal income tax purposes is critical; if treated as a corporation, cash available for distribution would be substantially reduced[157](index=157&type=chunk)[158](index=158&type=chunk)[159](index=159&type=chunk) - Unitholders are required to pay taxes on their share of income even if they receive no cash distributions, and certain transactions to reduce indebtedness may generate taxable income without corresponding cash distributions[165](index=165&type=chunk)[167](index=167&type=chunk) [Unresolved Staff Comments](index=40&type=section&id=Item%201B.%20Unresolved%20Staff%20Comments) No unresolved staff comments are reported -
