據美國聯邦公報消息，7月1日美國環保署（EPA）發布終期條例，當使用嵌入氧化亞銅聚合物發射頭的灌溉系統灌溉農作物時，豁免氧化亞銅在肉、奶、家禽、蛋、魚、貝類產品或灌溉作物內部或表面的殘留限量要求。本條例自7月1日起生效。
部分原文報道如下：
This regulation amends the tolerance exemption for copper in/on meat, milk, poultry, eggs, fish, shellfish, and irrigated crops when it results from the use of cuprous oxide embedded in polymer emitter heads used in irrigation systems for root incursion prevention. This regulation eliminates the need to establish a maximum permissible level for residues of copper resulting from this use of cuprous oxide.
