While not strictly required, consider opening up a separate discussion thread for this EIP so it is clear throughout the discussion what people are talking about. Having multiple EIPs (especially competing ones) that all use the same discussion issue can lead to confusion among participants as people end up not all discussing the same thing.

| For blocks where `block.number >= FORK_BLOCK`, the following changes apply. | ||
|
|
||
| 1. Remove the `SELFDESTRUCT` refund. | ||
| 2. Replace `SSTORE_CLEARS_SCHEDULE` with `SSTORE_RESET_GAS + ACCESS_LIST_STORAGE_KEY_COST` (4,800 gas as of EIP 2929 + 2930) |

It would be good to define what SSTORE_CLEARS_SCHEDULE is referring to more specifically. Maybe something like the following (note: I legitimately don't know what this is referring to, so the following is a guess/sample):
| 2. Replace `SSTORE_CLEARS_SCHEDULE` with `SSTORE_RESET_GAS + ACCESS_LIST_STORAGE_KEY_COST` (4,800 gas as of EIP 2929 + 2930) | |
| 2. When a storage value starts a transaction with a non-zero value and ends a transaction with a zero value, subtract `SSTORE_RESET_GAS + ACCESS_LIST_STORAGE_KEY_COST` (4800 at the time of this writing) from the transaction gas used accumulator. |

| ## Simple Summary | ||
|
|
||
| Remove gas refunds for SELFDESTRUCT, and reduce gas refunds for SSTORE to a lower level where the refunds are still substantial, but they are no longer high enough for current "exploits" of the refund mechanism to be viable. |

Recommend shortening this up. Think email subject line or forum thread title or GitHub PR title.
