The previous two posts have reported on the amount of abandoned mine land in Missouri and neighboring states, how much of it is high priority, how much of it has been reclaimed, and how much remains to be reclaimed.
Coal has been one of the world’s most important industrial fuels, and for most of the last 100 years it has been the primary fuel from which we generate electricity. One of the reasons America grew to be an economic powerhouse was because we had abundant energy resources, and coal was one of them. As of 2015, West Virginia, Kentucky, Illinois, and Pennsylvania were the largest producing eastern coal states, in that order. Because their coal is high in sulfur, however, some coal production moved to the West, where the coal is lower in sulfur. Wyoming is now the nation’s largest coal producer, producing 39% of the nation’s coal in 2015.
Missouri is a coal producing state, though our production has been small compared to some other high producing states. As Figure 1 shows, a significant portion of the state is underlain by coal. The majority of the coal veins are thin, however, and tend to be high in sulfur. Thus, coal mining never became the huge industry it did in some other states.
Coal mining began in Missouri in the 1840s. It peaked in 1984, when almost 7 million tons were mined. But since then, production has trended lower, and 233,898 tons were mined in 2016, a small fraction of peak production. In contrast, Wyoming mined 387.9 million tons, hundreds of times more. Figure 2 shows the trend since 1994. Currently, the coal used to generate Missouri electricity is about 90% Wyoming coal, 10% Missouri coal.
Other kinds of mining began in Missouri even earlier, as early as the 1740s. At one time, Missouri was the primary source of lead in the United States. As many as 67,000 acres of unreclaimed land were abandoned by the coal industry, and 40,000 acres by other mining operations.
Missouri’s land reclamation program was established by state law in 1974, when the Department of Natural Resources was created. But it got a big boost with the passage of the federal Surface Mining Control and Reclamation Act in 1977. This law provides minimum requirements for mines, funding, and oversight of state reclamation efforts.
As we saw in the previous post, some states have an abandoned mine land problem many times greater than does Missouri, and their reclamation efforts receive higher levels of funding than does ours. Funding has varied from year-to-year with budgetary woes and shifting priorities. But Missouri and other states have been working to reclaim abandoned mine lands since the 1970s. As we saw in the two previous posts, abandoned mine lands are classified into 3 broad categories. Lands that pose an extreme danger to health and welfare are classified Priority 1, and lands that pose a threat to health and welfare are classified as Priority 2. Land that has been degraded by mining operations, but which is not a threat to health and welfare, is classified as Priority 3. Priority 1 and 2 lands are classified as high priority. The law requires their reclamation before Priority 3 lands are addressed. In addition, the law requires abandoned coal mining land to be addressed before other types of abandoned mine lands, I’m not quite sure why.
Since the 1970s, mining operations have been required to obtain state permits in order to operate. Miners must pay a fee for the permit, and place a bond with the state, and they are required to reclaim their land when mining operations finish. Should they fail to reclaim the land, the bond is forfeited, and the funds are used by the state for its reclamation efforts. Because there is less coal mining in Missouri, fees collected by the Department of Natural Resources have decreased, and this is one reason that the funds available for reclamation have also decreased. (Missouri Department of Natural Resources, 2014)
As reported in the previous 2 posts, Missouri has made significant progress in reclaiming its abandoned mine land. But it is a very, very big and expensive job. Because the units to be reclaimed can be of so many different types, and because funding levels control the rate of reclamation, I think that estimated costs may give the best picture of what’s been accomplished and what remains to be done. By cost, Missouri has completed about 1/3 of its work to reclaim Priority 1 and 2 land. However, that does not include Priority 3 land. In 2017, Missouri accomplished $449,009 worth of reclamation work on Priority 1 & 2 lands. Given that there are $108,977,143 in uncompleted Priority 1 & 2 reclamation costs, at that rate, it will take Missouri 243 years to complete reclamation on Priority 1 and 2 land. Unfortunately, not all abandoned mine lands have been inspected. As they are inspected, unless Missouri devotes more resources to the job, the time to completion is likely to grow.
