Installed After May 12, 1971.
(a)
For any ferrous foundry installed after May 12, 1971, no person shall
cause or allow the emission of particulate matter, including fumes, to exceed
those emission standards specified for “New Devices” in Table 2102-1.
(b)
For any ferrous foundry installed or modified after June 15, 1974, in
addition to those requirements stated in (a), above, no person shall cause or
allow such a foundry to discharge into the ambient air any gas which contains
particulate matter in excess of 50 milligrams per dry standard cubic meter, or
0.022 grains per dry standard cubic foot.

Env-A 2404.01 Non-Sulfur Emission Standards For
Non-Ferrous Foundries, Smelters, and Investment Casting Operations Installed
Prior to or On February 18, 1972.
Subject to Env-A 2404.03, below, for any non-ferrous foundry, smelter or
investment casting source installed prior to or on February 18, 1972, no person
shall cause or allow the emission of particulate matter, including fumes, to
exceed the emission standards specified for “Existing Devices” in Table 2102-1.

After February 18, 1972. Subject to
Env-A 2405.03, below, for any non-ferrous foundry, smelter, or investment
casting operation installed after February 18, 1972, no person shall cause or
allow the emission of particulate matter, including fumes, to exceed the
emission standards specified for “New Devices” in Table 2102-1.

Env-A 2404.03 Calculations of Sulfur Dioxide Emission
Standards for Non-Ferrous Foundries, Smelters, or Investment Casting Operations.
(a)
For sulfur dioxides, the maximum allowable particulate matter emission rate
from non-ferrous foundries, smelters, or investment casting operations shall be
calculated by the applicable equation in (b) through (d), below, where:
(1) “X” means the total sulfur, CAS number
7704-34-9, burned in the smelter in pounds per hour; and
(2) “Y” means the emission of sulfur dioxide, CAS
number 7446-09-5, in pounds per hour;
(b)
For copper from smelters, CAS number 7440-50-8, multiply X by 0.2, as
shown in the formula below:
Y
= 0.2X
(c)
For zinc from smelters, CAS number 7440-66-6, raise X to the 0.85 power
and multiply the result by 0.564, as shown in the formula below:
Y
= 0.564 X0.85
(d)
For lead from smelters, CAS number 7439-92-1, raise X to the 0.77 power,
and multiply the result by 0.98, as shown in the formula below:
Y
= 0.98 X0.77

Env-A 2404.04 Visible Emission Standards for Non-Ferrous
Foundries, Smelters, or Investment Casting Operations.
(a)
Unless otherwise specified in this chapter, no person shall cause or
allow visible fugitive emissions or visible stack emissions for any non-ferrous
foundry, smelter, or investment casting to exceed an average of 20 percent
opacity for any continuous 6-minute period.
(b)
Opacity shall be determined in accordance with Env-A 807.

malfunction-based violation of Env-A 2402.02(a), Env-A 2403.02(a), or Env-A
2404.04(a) is alleged in a penalty action may raise an affirmative defense as
provided in Env-A 2103.03.
