The North Carolina Aggregates Association has two classes of membership, Producer Members and Associate Members.
Producer membership is open to any company engaged in the production and/or sale of sand, gravel, crushed stone or other aggregate products in North Carolina. Also, individuals, firms or companies not actively engaged in the production and/or sale of aggregates but who serve the industry with products or services are eligible for Associate Membership. The Annual Membership Dues, set by the Board of Directors, are calculated as follows:
PRODUCER MEMBERS:
By February 1st each year, every producer company reports the number of plants in each production class for the prior year. Each class has a ?”weighting factor” or “unit” value. The units are summed for all plants reported by a member.
| Class | Annual Production | Weighting Factor | Annual Dues Per Plant |
| A | Over 1,000,000 tons | 8 | $5,368 |
| B | 500,000 to 1,000,000 tons | 6 | $4,026 |
| C | 250,000 to 500,000 tons | 4 | $2,684 |
| D | Less than 250,000 tons | 2 | $2,120 minimum |
For example, a company with 2 Class A plants (2×8 = 16) and 1 Class B plant (1×6 = 6) would have 22 units.
To provide a means of balancing or equalizing the financial burden between larger and smaller producers, a discount system (I or II) is applied for companies with a large number of plants as follows:
- First 5 plants – Pay full amount
- Over 5 plants – Pay 1/2
- Over 10 plants – Pay 1/4
- Over 15 plants – Pay 1/8
This discount is applied when calculating the units per company and can be applied to 1) the number of units in each Class (Discount I) or 2) to the total number of units per company (Discount II) whichever provides the largest discount. Let’s take an example company with:
- Class A – 8 plants
- Class B – 3 plants
- Class C – 2 plants
- Class D – 1 plant
| Class A | Class B | Class C | Class D | Total Units | |
| Plants | 8 | 3 | 2 | 1 | |
| No Discount | 8 x 8 = 64 | 3 x 6 = 18 | 2 x 4 = 8 | 1 x 2 = 2 | 92 |
| Discount I | 5 x 8 = 40 3 x 4 = 12 8 52 |
3 x 6 = 18 | 2 x 4 = 8 | 1 x 2 = 2 | 80 |
| Discount II | Total number of plants = 14 i.e. 5 x 8 units = 40 5 x 4 units = 20 4 x 2 units = 8 14 68 |
68 |
Hence, Discount II yielding 68 total units will provide the largest discount. Company dues would then be 68 x $671 = $45,628.
There are no maximum dues. Minimum producer dues are $2,120. Producer members may elect to pay quarterly. Payment for the full year is encouraged.
ASSOCIATE MEMBERS:
All Associate Members pay a flat $1,130 per year.
