I would like to address a couple of points. I apologize for not having read the entire thread, but this is my take on the situation.
Mandatory retrofits. The new regulations should only apply to new equipment. Retrofits are expensive, unfair to owners of products purchased under less restrictive regulations, and can often cause reliability to suffer versus new equipment designed around the new technology.
The Law of Diminishing Marginal Returns (LDMR). This is an economic term used to describe the idea "more is not necessarily better". You can do a quick search to find out more information about it. Essentially we are running up against the LDMR which can be characterized by reduced benefit per unit of cost. As an example, you can apply the recommended amount of seed per acre for grass. Applying twice as much will not get you twice as much grass, but costs you twice as much. This is the situation our environmental regulations have us in currently. When the environmental regulations first came into play, it was pretty inexpensive to significantly clean up emissions, spills, releases, and so forth. As the laws tightened, and the easy fixes were implemented, the cost/benefit ratio began to get unfavorable. In other words spending exponentially more money for less actual benefits.
Laws like this will hurt businesses significantly in that it will be expensive for them to have to retrofit the equipment, or buy brand new equipment. Prices for their services will go up, and probably a lot of smaller businesses will be priced right out of the market by the significant increase in the cost to do business.
This applies to manufacturing, as well as the service industry, or any other industry that falls under these regulations. In terms of manufacturing it can increase the cost of making products, making it more favorable to cash in on the cheap labor and lax environmental and occupational safety regulations in places like China. The economy does not need such an increased burden on it at this time. Thanks to LDMR, the tightening of environmental regulations should temporarily be suspended until such a time as China and other developing nations comply with laws similar to ours.
It is a noble goal to reduce pollution, but from an economic standpoint, it will increase the price of a lot of different products and services, which gets passed on to the consumer. If the consumer can't or won't pay the increased price, businesses close and unemployment will go up as a result. Not a good solution, since we have an economy to worry about.
My argument can be summed up with two bullet points:
*Regulations need to be phased in for new equipment and existing equipment needs to be grandfathered as-is in order to not be too disruptive on the economy.
*LDMR is part of what helps cause manufacturing and other jobs to go elsewhere, because it costs too much to keep up with the strict regulations here versus many other places of the world.
