Sec. 180.1021  Copper; exemption from the requirement of a tolerance.

    (a) Copper is exempted from the requirement of a tolerance in meat, 
milk, poultry, eggs, fish, shellfish, and irrigated crops when it 
results from the use of:
    (1) Copper sulfate as an algicide or herbicide in irrigation 
conveyance systems and lakes, ponds, reservoirs, or bodies of water in 
which fish or shellfish are cultivated.
    (2) Basic copper carbonate (malachite) as an algicide or herbicide 
in impounded and stagnant bodies of water
    (3) Copper triethanolamine and copper monoethanolamine as an 
algicide or herbicide in fish hatcheries, lakes, ponds, and reservoirs
    (4) Cuprous oxide bearing antifouling coatings for control of algae 
or other coatings for control of algae or other organisms on submerged 
concrete or other (irrigation) structures.
    (b) The following copper compounds are exempt from the requirement 
of a tolerance when applied (primarily) as a fungicide to growing crops 
using good agricultural practices: Bordeaux mixture, basic copper 
carbonate (malachite) (CAS Reg. No. 1184-64-1), copper ethylenediamine 
complex, copper hydroxide (CAS Reg. No. 20427-59-2), copper lime 
mixtures, copper linoleate (CAS Reg. No. 7721-15-5), copper octanoate 
(CAS Reg. No. 20543-04-8), copper oleate (CAS Reg. No. 10402-16-1), 
copper oxychloride (CAS Reg. No. 1332-40-7), copper sulfate basic (CAS 
Reg. No. 1344-73-6), cupric oxide (CAS Reg. No. 1317-38-0), and cuprous 
oxide (CAS Reg. No. 1317-19-1).
    (c) Copper sulfate pentahydrate (CAS Reg. No. 7758-99-8) is exempt 
from the requirement of a tolerance when applied as a fungicide to 
growing crops or to raw agricultural commodities after harvest.
    (d) Copper (II) hydroxide (CAS Reg. No. 20427-59-2) is exempt from 
the requirement of a tolerance when applied to growing crops or to raw 
agricultural commodities as an inert ingredient (for pH control) in 
pesticide products.
