A quarry a mile out, and the same operator again five miles north
The Mine Safety and Health Administration lists the Winfield Quarry of New Enterprise Stone and Lime here, a crushed-limestone operation with 9 people on it, 1.27 miles west of the middle of the village. A mile is close enough that the pit and the village share a road rather than a district.
The same operator works the Lewisburg Quarry 4.98 miles north with 16 people. Two limestone pits under one company inside five miles is a single business rather than a market.
East and south the rock changes to sand. The Northumberland sand plant is 6.32 miles east with 5 people and the Montandon sand plant 6.62 miles south with 8, both worked by Central Builders Supply, and a rail yard sits 2.34 miles east.
The county owns nearly two-thirds of the restrictions
Those pits sit on a network the county has an unusual grip on.
Union County maintains 26 structures of its own and posts 6 of them, so the county road department is both the smaller network here and the one that carries most of what constrains a truck.
Nothing is restricted for the first five miles in any direction. The nearest below-legal crossing is 5.08 miles north-east and it rates 4.5 tonnes, which is under an empty tandem dump, and the lowest in the circle is the same figure 7.35 miles out.
A clear five miles, then two crossings nothing commercial uses
That combination is worth stating plainly. The first five miles out of this village are unrestricted in every direction; then two Union County bridges appear, 5.08 miles north-east and 7.35 miles out, that no commercial vehicle crosses at all, loaded or empty.
It makes the geography binary rather than graded. There is no middle band here of crossings that take a truck part loaded and let it through — a lane either runs clear or it meets a 4.5-tonne bridge and stops, and the answer is to go round rather than to take weight off.
For a seller that is easier than it sounds. It means the question is which way a truck leaves rather than how much it can carry, and working that out is our job rather than yours.
Limestone one way, sand the other, and different dust in each
So a truck from this village worked one of two materials and they are not interchangeable. Limestone off the Winfield Quarry 1.27 miles west is a carbonate rock, and quarry work in it carries a carbonate exposure profile rather than a quartz one.
The sand plants east and south are the other case. Sand is substantially silica by design rather than a rock that happens to contain some, which is where the Mine Safety and Health Administration respirable crystalline silica rule reaches its sharpest application — a permissible exposure limit of 50 micrograms per cubic metre with an action level at half of it, and the compliance date for metal and nonmetal operations now past.
For the vehicle the difference shows in the filters, seals and brake hardware rather than anywhere obvious. Site-specific hazard awareness training is required for over-the-road delivery drivers before work at each mine site, so a driver who ran into several of these often has the paperwork that says which.
One operator working two pits nearby means fleets here tend to turn over together rather than one truck at a time.
- The crossing 5.08 miles north-east rates 4.5 tonnes and nothing commercial uses it. Going round is our problem — we come out and drive it away, we come out and tow it, we buy it remotely and arrange the tow, or you bring it to us.
Between the Winfield Quarry 1.27 miles west and the Montandon sand plant 6.62 miles south they turn up steadily.
